As the meeting organizer, you are in control. By default, only you have access to the smart playback. Within a single click, you can share the meeting smart playback with all attendees. Each meeting will also have a public URL with access only to that meeting, which can be shared with others.
Currently, only the organizer can bookmark key moments during the meeting. Would you like the option for attendees to save their own bookmarks? Please email firstname.lastname@example.org and let us know.
