A meeting with a lead is sent as an invitation from the salesperson's own calendar: Google Calendar with a Google Meet link, or Outlook with a Microsoft Teams link. The meeting also appears on the lead's timeline in Desk, with the agenda the guests see.
Meetings can be rescheduled or cancelled from Desk, and the invitation updates accordingly. If an AI assistant proposes the meeting, nothing is sent until a person approves it under Approvals in Desk. You can see each proposal's state there: awaiting approval, sent, rejected, failed or expired.
