Set Background Color for adaptive Icons

I know how to remove the unsightly white border when the phone uses adaptive icons.
However, to achieve this you need to remove the background of the icon. This will cause it to be white.

I would like to have a setting in Kodular to change the icon background. This would increase the quality of the apps by a lot. Also, Android 11+ uses a start animation that also uses this white background, which doesn’t always match the app design.
