[PopupMenu] Apply a shapeAppearance style to a PopupMenu

I am using the latest version

com.google.android.material:material:1.1.0-alpha09

According to documentation it is possible to customize the component shapes using the shapeAppearanceOverlay attribute in the style.
These components should be supported:

• Bottom Sheet
• Button
• Floating Action Button
• Card
• Chip
• Dialog
• Menu
• Text Field

I am able to apply the attribute to these components except the Menu, in particular PopupMenu. I was looking for it in the material themes but I didn’t find it.
I tried something like that, but it doesn’t work:

  <!-- Popup Menu -->
  <style name="Widget.MyApp.PopupMenu" parent="@style/Widget.MaterialComponents.PopupMenu">
    <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MyApp.PopupMenu</item>   
  </style>

  <style name="ShapeAppearanceOverlay.MyApp.PopupMenu" parent="">
    <item name="cornerFamily">cut</item>
    <item name="cornerSize">32dp</item>
  </style>

Please support this. I am using the Solid Explorer and they customized it. It looks is so nice.

Just a side note: As expected, setting custom popup background (AKA the “hack”) no longer works with M3.
