A claim is only coherent if you can say what it means. So far free will is defined as “like, you know, free will” or words to that effect. I don’t think you can do better, which is why I claim it’s incoherent.
I gather that in your view, free will resides in the soul, not the brain, though the soul has access to the information and processes of the brain and injects its decisions into the brain. Correct? But what happens in the soul when it chooses? Apparently nothing causes the soul to choose a certain way, nor is it random. But what is it, actually?
And how does that relate to the brain processes that seem to happen during choice?
