According to this support article:
When you upload an app bundle to App Distribution, it’s exported to Google Play to generate an APK that's optimized for your tester's device configuration.
But this answer in Firebase documentation:
AAB builds you upload to App Distribution do not appear in your Google Play developer account (this includes App Bundle Explorer and internal app sharing).
I would like the AABs uploaded to Firebase by my CI to be available in the Play Store, but they're not. Which article is correct? Is it possible to make it work? I would prefer to not use Fastlane.
