Cvent Studio handles Speaker requests in the form of 'knocks'. There are 2 types of requests that a Speaker can make.
1). Request to enter the Studio
2). Request to share their screen
Each of these requests will come through to the Host in real time. So, what happens if there is no Host in the Studio to answer those knocks? That's where the Waiting Room and Notification queue come into play.
Speaker Experience
The Speaker will arrive at the Guest Invite Link and enter their name. This will create an entry request which gets queued up for the Host. The screen then advances and sits in the 'Waiting Room' until the Host accepts the request. Once they do, the Speaker can select their Video and Mic and continue filling out their information.
Host Experience
When a Host first enters a Studio instance, if there are entry requests waiting to be approved, they will appear in the top right of the Studio for 5 seconds. The requests/notifications will then disappear.
To view all pending requests a Host can click on the new Notifications 'bell icon' at the top right and Approve/Deny any pending requests.
The notification modal allows you to approve/deny requests one-by-one or approve them all at once. The Hosts can also map the knock requests (to enter the studio) from Speakers to their existing Speaker placeholders by clicking on the drop-down key appearing next to the Approve button.
By default, Studio will map the Speaker join request to an existing placeholder if the name of the placeholder and the name of the Speaker match.
