Free choice in quantum theory

Good week,
I read in your book, The Science of Freedom on Saturday, about finding gaps in physics in favor of free choice.
In quantum theory, you present that there is ontic freedom (a physical event is created without a cause) but it is random because the particle is distributed according to some distribution.
I would be happy if you would point out a problem in the following attempt to introduce free choice into quantum theory:
I move my hand as a result of electrical currents resulting from an electron in the brain collapsing to a specific point that caused an electric field.
The collapse took place for no reason, but it did have my purpose.
The distribution of the wave function is determined by human choices.
That is, the behavior of the particles determines their distribution, and their behavior stems from the future purpose/reason of humans.

Once there is a purpose, it is not a random distribution. In this regard, there is no difference between a cause and a purpose.

I didn't understand,
Why in this case is there no difference between cause and purpose?
There is a possibility here to introduce freedom into quantum theory with a purpose (not a cause) and therefore it is freedom and not randomness.
Regarding the argument about the distribution, I wrote above.
Where am I wrong?

Because neither cause nor purpose is random. If there is a given quantum distribution, it dictates the distribution of outcomes. And if a person chooses these outcomes according to his various decisions, it should not correspond to the quantum distribution.
I don't see what is unclear here.

From what I remember, you also claimed that human choices are distributed in some way (the distribution is not fixed, human choices determine the distribution).
So this could also be the case here, humans are the ones who determine the quantum distribution.

First, the Schrödinger equation determines the quantum distribution, and it does not take into account any human choices. Second, if our choices determine the quantum outcomes – we are back to what I was saying. You cannot fit free will into the framework of quantum theory. There is a choice, and it activates the physical system (quantum or classical, it doesn't matter).

I think I understand,
In fact, even a process that includes a collapse of the wave function is supposedly “causal” because there is something that caused the collapse (measurement), and therefore there is no freedom here either (at most randomness).
Thank you.
