While I am using min 14 and target SDK 30 the above wrapper throwing below error

Probably lacking the SYSTEM_ALERT_WINDOW permission
Manifest.permission | Android Developers
SYSTEM_ALERT_WINDOW - How to get this permission automatically on Android 6.0 and targetSdkVersion 23 - Stack Overflow

The following is my best guess - others may have a better understanding of this!

Add the manifest entry
AddPermission(android.permission.SYSTEM_ALERT_WINDOW)

You may need to ask for the permission at runtime.
Dim rp As RuntimePermissions
rp.CheckAndRequest("android.permission.SYSTEM_ALERT_WINDOW")
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)

Draw on top of other apps permission
