Pause app option isn't available on launchers

I know the title may sound a bit misleading, but this is my situation: I'm interested in using a custom launcher on my device, but the problem is that there's this option to "Pause app" that I want to use to prevent some apps from using my battery or getting my location or something, but I can't do that on custom launchers (for obvious reasons). Does this thing actually works or there isn't any actual difference?
