System
Android Version: 14
Custom ROM: LineageOS 21 with microg (microg LoS)

microG
microG Core version: i don't see any app named core in my app list, but microG Services is 0.3.7.250932
microG Self-Check results: All ticked except "permission to find accounts on the device" and "permission to interact with work profile"

clicking permission to find accounts on the device doesn't do anything

Additional context
Add any other context about the problem here.

No source files or tests are identified. First reproduce the bKash Merchant OTP flow on Android 14 with microG Services, then trace the Android SMS Retriever handling and compare it with the expected permission popup. Done means the popup appears after the OTP SMS is received, without breaking the working flow in other bKash apps.
