Maybe this functionality exists, just have not found it.
I'm familiar with Private meeting rooms and how to apply passcodes and how to enter passcodes before entry.
However, what about the scenario of locking a meeting once the "invited" participants have arrived? On the PC client, I see there is a Do Not Disturb function. I've tested that while in a meeting, and it allows others to still join the meeting.
Am I missing something or is there no way to lock a meeting on the fly for the simple reason of keeping people from accidentally joining?
If the functionality does not exist, please join me in voting to add the option.
