Fragment add exit custom animation not working working when fragment is Added Android

Question

The custom exit animation works for replace but not for add

getNavFragment()
        .childFragmentManager
        .beginTransaction()
        .setCustomAnimations(
            enter,
            exit,
            popEnter,
            popExit
        )
        .add(R.id.fl_fragment_container, fragment, tag)
        .setReorderingAllowed(true)
        .apply {
            if (shouldAddToBackStack)
                addToBackStack(tag)
        }
        .commit()
