The Host Tools Icon
Select this icon to quickly review and change session settings such as allowing participants to share screen or to enable/disengage the Waiting Room.
The Security Badge
Select the shield/badge icon on the top-right of the meeting interface to quickly review meeting details, such as the meeting ID or invitation link. Select the option "Security Settings Overview" to reveal more information.
