How to set permissions on a folder or report in Microsoft Report Manager using t-sql?

Question

Transact SQL

Good day.
Tell me how to correctly set the rights to a folder or report in Microsoft Report Manager using a query.
I understand the algorithm of actions as follows:
1. We read the identifier for the user (s)
2. We collect the policyID
3. We apply this policyID to the desired directory or report
There are not enough skills, maybe someone has already encountered such a task?
