Very good extension Taifun. I found only an annoying thing (I am just testing and it is not very important in my case): calling SupportedLanguages returns the error " Attempt to invoke virtual method 'java.lang.String android.content.Intent.resolveTypeIfNeeded(android.content.ContentResolver)' on a null object reference Note: You will not see another error reported for 5 seconds." Tested on Android 11.
I now updated the extension and tested it using the companion app on Samsung Galaxy A51 running Android 11
