Those kind of apps have a special place on my phone: petercxy's shelter (don't install it from play store because in order to meet the Google requirements it has been nerfed). Apps installed there use a dedicated throwaway Google account and are completely disabled with a toggle on my launcher. (Lawnchair 2 has a toggle in the drawer for it)

If an app is installed in shelter it's on a completely separate partition and can't access any file or photo on your main one. And once you quit, they are all disabled like if the phone is turned off
