Yes, you have access to a lot of information about the space:
- The call status badge notifies you of the number of people in the space
- If you select the space in the Spaces view (or Activity view if it is listed), then you can see who is in the space by looking at the list of members. Those in the space are highlighted in green. Guests in the call are also listed here.
- You can chat to find out if it is convenient for you to join – like knocking on a door before entering a room
