How exactly does the bitcoin protocol work?

Question

blockchain

I deal with the crypt and basically everything is clear, but there was a question that Google does not answer. On the Internet there is about chain bifurcation, about confirming transactions, and so on, but I could not find this moment, I even looked in the description of the protocol specifications, but apparently I was looking badly.
I am interested in this moment: The
pool / solo miner works and at some point finds a solution for the block. What happens next? What and where does the pool send? How does the network determine to whom exactly to accrue a reward for a found block? That the block found exactly pool A, and not pool B or C.
If possible, in more detail.

Answer 1

Question removed. I saw the information about the generation transaction.
