I mean, I'm looking through the permissions now and don't see anything that's not arguably needed to make it work:

- Calendar (it can set up reminders in group chats and calendar)

- Camera/Microphone (to take pictures and videos to put in group chat)

- Contacts (to get a list of contacts! Also see SMS capability below)

- Location (you can send your location in a chat)

- SMS (it can act as an SMS client as well as FB chat)

- Storage (store received pics/videos, and access existing pics/videos)

- Telephone (to detect when you get an incoming call so it can handle any active activities (think if you're already on a video call)).

And as others have noted, you can disable most of these if you don't want them on recent Android versions.
