Solution:

There are three roles within Webex Meetings, which are referenced below. 

• Host Role:  The host is the person who schedules, starts, and ends the session or records a session. A host can also assign roles to other participants in the session. The host can be reassigned once in a session.
• Cohost: Because the Cohost role provides privileges similar to the host role, Cohosts can help to improve meeting productivity. If the host is running late or can't attend, a cohost can start and manage the meeting. Cohosts can also assist the host with meeting management, which is useful for larger meetings.
• Presenter: Responsible for sharing and annotating presentations, whiteboards, documents, and applications in a meeting.
• Note Taker: A single note taker can publish notes at any time during the meeting or can send a meeting transcript to all participants.
• Closed Captionist: Responsible for publishing captions in real-time during the meeting and can send a transcript containing the captions to all participants.
• Attendee Role:  Any person attending the session who is not already identified as a Presenter, or host. Attendees are typically who the meeting information is being presented to.
