Mio can only view messages in spaces/direct messages in which the app is a member. If the Mio app is not in the conversation, it won't be able to view any of its contents. We never request more permissions than necessary to make universal channels function as intended.

See which permissions are requested by the app for Connect Platforms (enterprise customers only).
