Yeah no, sometimes you need screen sharing in the "chatting app"

A lot of university clubs are on Discord, and my cyber club does tutorials and labs on the weekends where the leader screen-shares. It's nice because you can see the video in real time and ask questions whenever, rather than watching a pre-recorded video and having to hope you have no issues while following along.

I mean, this is literally why Zoom blew up so much during COVID. Real-time learning works more than asynchronous learning for a lot of people.
