Yes, we agree on that. Determinists would have to deny it. They would have to say it only "seems" that way to us, but that the deeper truth is that the so-called "mind" is just an "epiphenomenon" of the material brain. Thus, that "mind" is not actually explicatory of anything in a causal chain.
I wrote "brain". I didn't write "mind".
A brain is just a piece of meat, if there's no mind in it. Even corpses still have brains.
A brain is some arrangement of atoms which can process information and make decisions.
The brain may be defined as "a particular arrangement of atoms." But so may a goat, an aqualung, and an armchair.

So that description doesn't tell us enough.
But yes, in one sense, the "brain" is the
material entity. However, its ability to "process information" and "make decisions" is clear evidence of a "mind," not just a "brain."
No determinist problem with that, is there?
For the Determinist, the "brain" is all there is. The "mind" is the epiphenomenal part, the "emergent" part. But there's no Deterministic description of how the two differ: the assumption is that, whatever the "mind" actually is, when we dig down, all we are going to find is that it's a quirky kind of operation of "brain," but not different from "brain."
That doesn't follow. It presumes a developmental narrative we do not have. "Emergence" is not observable, not reproducible in a lab, and not testable now. Consciousness is testable, now, after the fact; but its manner of origin is not. So IF mind somehow "emerged" from brain development, we have no idea HOW such a thing could be possible.
Again, I didn't write "mind".
And science has not problems observing "emergence".
It depends on what is "emerging." "Emergence" is really such a general term that it's unhelpful descriptively.
Here is just one example:
Emergence refers to the existence or formation of collective behaviors — what parts of a system do together that they would not do alone.
In describing collective behaviors, emergence refers to how collective properties arise from the properties of parts, how behavior at a larger scale arises from the detailed structure, behavior and relationships at a finer scale. For example, cells that make up a muscle display the emergent property of working together to produce the muscle's overall structure and movement. A water molecule has emergent properties that arise out of the properties of oxygen and hydrogen atoms. Many water molecules together form river flows and ocean waves. Trees, other plants and animals form a forest.

This illustrates the point well. One can apply the word "emergence" to practically anything, from plants to rivers. But this is quite a different thing than when we talk about the mind-brain problem, because unlike the mind-brain problem, the "emergence" in this case is not simply more-of-the-same, as when a "river" forms an "ocean," or as when an "oak" emerges out of an "acorn." Rather, consciousness is a totally different, totally unexpected property that is said to "emerge" suddenly, completely, and totally differently from the alleged substrate from which it is said to "emerge." Thus, to say that "mind" "emerges" from matter is to say that something totally unlike the material from which it "emerges" suddenly "emerged" -- complete, ready to do its work, and somehow not comprised of the same materials from which it "emerged."
Think of it this way. At one time, the universe, we are told, was composed of nothing but basic elements...like hydrogen molecules, or oxygen molecules, or quark-gluon plasma, all floating around. None of that was "mind," we are told. (And we can still see that it wouldn't be, too: the hydrogen and oxygen we find today has no "mind" of its own, either. So if basic elements are all there was, then nothing was sentient: nothing had "mind.") Then there was an explosion, called "the Big Bang," and, after a long time, life "emerged." We don't know how, we can't reproduce it in a lab...despite having tried desperately to do so, for many years now...and we had no instruments in place to detect this alleged "emergence." So it's just an assumption, a "reading-backward" of events, a sort of speculative deduction.
Likewise, the mind-brain problem. The "emergence" explanation tells us that when the brain in the life that miraculously "emerged" from basic, non-sentient elements developed to an unspecifiable level of sophistication, then "mind" had to have just "emerged" from that lump of meat in the cranium. It just "popped out," so to speak, unexpectedly, not gradually, conscious and ready-to-go, as the climax of some sort of assumedly-material rearrangement we have to admit we just don't understand.
That's the "emergence" theory, specifically as it relates to the mind-brain problem. As you can see, it's not about rivers and trees, and not about things that "emerge" gradually, predictably, or of-the-same-order as the thing from which it is said to have "emerged."
Thus, even from a purely Materialist point of view, "emergence" is a non-explanation. It doesn't actually tell us what the process was: it's just a label for "we don't know how this thing happened, if it did."
We don't know lots of stuff. That doesn't mean that the thing doesn't exist or that there is no emergence.
No, but it means a couple of other things. It means we have no explanation of how "emergence" could even happen. It means we have no certainty it even could happen. It means we're thrown back on a kind of magical thinking: that when brains just get to a certain stage of sophistications, "minds" pop out of them, like a jack-in-the-box.
To know that the "emergence" explanation of mind-brain could work, we'd first have to know how life could "emerge" from inert matter. Then we would have to know how life could become "sentient." Then we would have to know how sentient life of a low order (paramecia, fish, dogs) could suddenly generate higher-order consciousness as we see it in humans, such as self-awareness, the ability to conceptualize and abstract, the propensity to moralize, the capacity to do mathematics, and the higher intellectual functions of reason and logic...and the ability to ask and consider philosophical questions.
And none of that do we know.
So for the moment, the "emergence" explanation has nothing to it. And to speculate,
"Well, one day it will," as, say, the Eliminativists do, is merely to prophesy, not to do science.
