If using Google Duo with App Inventor 2 is possible, you would have to use an intent.  App Inventor uses intents by using ActivityStarter.  

I do not think this is possible Madev.   Why?   See what Android Studio developers using the professional compiler say https://stackoverflow.com/questions/39925337/what-intents-or-apis-does-googles-duo-app-for-android-support
