Can I know when Android apps use certain permissions?

Hello! I'm asking this question because I was curious about the Samsung's 'App Permission Monitor' digging on pjhjohn's blog.

In the detailed function, the app permission monitor notifies users every minute when certain permissions are used when not using the app, but how do you know if the app permissions work and what additional permissions do you need to detect them working?

If it's a result that comes out right after searching, I'd appreciate it if you could tell me which search word to enter!
