The Owner is the only user who can configure and modify the session. They can be seen as the session’s administrator or CEO. It is their responsibility to organize, anticipate and structure the session in such a way that Attendees can easily consume it or contribute to it.
The Owner is also the only one who is able to change others' roles, such as turning an Attendee into a Speaker by using the Controller. Hovering over an Attendee's avatar in the Participants block displays their video stream and a call to action to change their role from Attendee to Speaker.
Note: We call all those involved in a session participants.
The Owner + all Attendees + all Speakers = participants
