Answer 1

You should either use a ViewPager/ViewPager2 with NavHost fragments or implement BottomNavigationView with extension functions Google provided, which basically tags fragments and add them with NavHostFragment.create().

NavHostFragment takes care of childFragmentManager and back stack management. You can check out examples here if you wish.
