To Reproduce
Steps to reproduce the behavior:

1. Go to 'Settings', 'About'
2. Tap 'Made by Zeus WPI' twice to unlock Zeus mode
3. Exit 'Settings', go to the new 'Zeus mode' entry
4. Fill in credentials in 'Manage login data' in the top right of the app
5. Press 'Order', then 'Scan'
6. It now logs com.google.mlkit.common.MlKitException: Code scanner module is not supported on current Google Play Services version, please upgrade. in logcat

Expected behavior

I expect a barcode reader window to show, letting me scan barcodes

System
Android Version: 12
Custom ROM: LineageOS 19.1 MicroG

microG
microG Core version: 0.2.24.214816
microG Self-Check results: All ticked

Additional context

The app is open-source, that might make testing easier. See https://github.com/ZeusWPI/hydra-android

I think MLKit has not (yet?) been implemented in microg.

Same here, for my (currently useless) banking app:

I think MLKit has not (yet?) been implemented in microg.

It seems that is supported old Mobile Vision API only (and only for barcode), also would be a good idea support tensorflow on microg, MLkit is strongly based on tensorflow and gms offer tensorflow API for app that need it. But honestly this is the game of the mouse and the cat, google deprecate API very fast and replace it in time seems VERY difficult for a FOSS project.
