The restriction of being limited to Google Play and not other app stores implies the implementation is part of Google Play Services, and not included in AOSP
So I was curious if that’s how it’s implemented on Android - I know Google loves moving features out of AOSP
However, things like Android-Password-Store used Accessibility services through F-Droid for autotyping back when I used it
So, trying to understand what has been locked down, since I’m planning on going back to GrapheneOS
