Ok, I checked on my Android 9 device (I had previously tested on an Android 5 device.)
We have to add this line to the Manifest for API >= 28:
<uses-permission android:name="android.permission.REQUEST_DELETE_PACKAGES"/>
To customize the Manifest see here:
I'll ask the extension developer to add this permission to the Manifest.
He'll do it very quickly, as I know him.
