In the meeting overview, the admin can log external guests who will be joining the meeting in the Attendees section. Click the "Invite Guests" button and enter guest names and email addresses. Guest avatar is indicated by an outgoing arrow.

Admin could also track external guests' attendance in the Minutes tab.

Please note that guests will NOT have the following privileges:

If the Guest requires access to your portal to view documents in a meeting, Admin could use a user license to invite them as a non-member to the space.
