1. Trigger a ‘toggle pin’ when the media gallery is opened (for now)
2. Display the `threadInfo.pinnedCount` somewhere visible, for the test I displayed it right by `ChatThreadListItem`
3. Open the media gallery (to pin a message) on an admin user, and confirm the other account part of the thread receives the updated pin count
4. Confirm the permissions by trying to doing the same on the non-admin account and having an `invalid_credentials` server error in my logs
5. Validate the same, but for unpinning, where the pinned_count should decrease each time
