I get that, but it's also designed for sharing your entire laptop screen, so you'd have to either switch back and forth between code and chat, or take up half the screen with your chat app, both of which seem like they would be pretty disruptive to the actual screensharing.

It seems like it would be better to just send a screenshot and then discuss, so the other person doesn't have to watch you typing messages to them instead of looking at the actual thing you want to share.
