Hey @shwoseph,
Thanks for reaching out about this, and cool idea!
If you’re interested in capturing when a participant started and stopped sharing their screen, you can get this information in near real-time from our Get Sharing/Recording Details of Meeting Participant Endpoint, within the participants > details object:
While we don’t have an in-meeting alert function as you’ve described, you could get creative and potentially use this in conjunction with the inMeetingServiceListener in our Web SDK. Perhaps you could mute the participant (though I realize this is not the same). You can find all of the available in-meeting methods in our reference here.
Let me know if this helps!
Best,
Will
