While hosting a meeting, users add conference rooms as their location and during the meeting, they can go to conference rooms and press the big Green Join Button to start the meeting.
Now, meetings and events are used interchangeably by users. When scheduling the events, there is no option to select 'location' as conference room for Event hosts. Hence, the big Green Join Button is not available on the room device.
Enable this feature for events to make it a seamless experience for Event hosts.
