I am trying to style the Android's options menu. But, I cannot figure out how to change the background color of the popup menu.
I want to get rid of the white borders or to change the color of the borders.
I tried the following things: 

```
 <style name="DarkTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        ...
        <item name="android:popupMenuStyle">@style/MyActionBar</item>
        ...
    </style>
<style name="MyActionBar" parent="Widget.AppCompat.PopupMenu">
        <item name="background">@color/black</item>
        <item name="backgroundColor">@color/black</item>
        <item name="backgroundTint">@color/black</item>
        <item name="android:colorBackground">@color/black</item>
        <item name="android:background">@color/black</item>
        <item name="android:backgroundTint">@color/black</item>
        <item name="android:popupBackground">@color/black</item>
        <item name="popupMenuBackground">@color/black</item>
    </style>

```
