Resolution

For Android on API Level 31 and above, the READ_PHONE_STATE is required. You need to have the READ_PHONE_STATE permission and you need to directly request the permission from the user. It is tagged as Protection level: dangerous which is similar to the permission requested for RECORD_AUDIO.
