Setting a vector as the background of a FAB

I have a problem getting to display a vector or mipmap as the background of a Floating Action Button. Does anyone know what might be going wrong here?

xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools"      <com.google.android.material.floatingactionbutton.FloatingActionButton                 android:id="@+id/nationality"                 app:srcCompat="@drawable/flag_united_states_of_america_"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:layout_margin="10dp"                 android:backgroundTint="@android:color/transparent"                 android:layout_alignParentRight="true" />
