Group Policy not working on Windows 10?

Question

Group Policies

Hello, I have a strange situation. Task: add the domain administrators group from the ABC domain and the domain administrators group from the CBA domain to the local administrators group on user computers.
From the side of the domain (to which the computers are now connected), a group policy was created and applied to the necessary computers.
From the side of the user computer, the policy was applied, but did not work. That is, there is no result. Filters were not applied. GPO applied on the necessary OU with computers.
What could be the problem? Thanks in advance for your replies.

I could be wrong, but I don't think it works that way. I also came across a similar one, and in my opinion, I got out of it like this: I included the admins of domain B in the group of domain A, and I "stuffed" this group on local computers.
