Android navigation component animate go back from activity to fragment

Question

The animation when I am going from a fragment to an activity is working fine but when I click back it returns without the custom animation I insert. The same if I make the navigation from a fragment to another with the same animations works fine. Here is the action code I am using:

         <action
                android:id="@+id/toTicker"
                app:destination="@id/tickerActivity"
                app:enterAnim="@anim/slide_bottom_up"
                app:exitAnim="@anim/slide_up_bottom"
                app:popEnterAnim="@anim/slide_bottom_up"
                app:popExitAnim="@anim/slide_up_bottom"/>

As per this issue, you need to call the static ActivityNavigator.applyPopAnimationsToPendingTransition() method in your other activity to get the pop animations to apply - it should be called directly following when you call finish() or as part of callbacks to onBackPressed() (which internally will call finish()):

override fun onBackPressed() {
    super.onBackPressed()
    ActivityNavigator.applyPopAnimationsToPendingTransition(this)
}

Updating the documentation to specifically call this out is being tracked in this documentation issue.
