How to fine-tune the termination of disconnected sessions?

Question

RDP

Greetings!
The task is not as simple as it might seem at first glance) Yes, I know about the GPO, about the configuration of the remote desktop session host and about the settings for each user individually, but this is not it. Once upon a time, I googled one solution - some kind of snap-in (?) is launched in which you can fine-tune the whole thing: for example, select a user or user groups that will not be disabled or will be, but after a time different from the time of other groups and users. And I not only googled this solution, but also applied it. Now you need to add more users to the "privileged" group, but I forgot how to do it) And Google only offers the options listed above. Remind me, please, what kind of equipment this is, maybe someone has come across this.
