'Can I apply popEnterAnim when I popUpTo a destination?

I have a NavGraph like below. Why I CANNOT execute the popEnterAnim when popUpTo the graph starting destination?

   <?xml version="1.0" encoding="utf-8"?>
    <navigation xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/a_nav_graph"
        app:startDestination="@id/fragmentA">
        <fragment
            android:id="@+id/fragmentA"
            android:name="com.FragmentA">
  
            <action
                android:id="@+id/action_a_to_b_nav_graph"
                app:destination="@id/b_nav_graph" />
        </fragment>
        <include app:graph="@navigation/b_nav_graph" />
        <action
            android:id="@+id/action_a_nav_graph_pop"
            app:popUpTo="@id/a_nav_graph"
            app:popUpToInclusive="true"
            app:popEnterAnim="@anim/slide_out_buttom" />
    
    </navigation>
