I wouldn't really say their client works in that sense considering how notorious it is for flunking out in completely random ways (i.e missing push-to-talk release events, suddenly deciding your speakers or mic don't exist, not lighting up people who are speaking, the UI randomly blanking out, etc). It's probably the worst of the bunch in terms of bugs other than maybe Skype. Not that anyone picks their chat/VoIP client based off that either way; we all happily used the 2011-era Steam client, and that was a legendary kind of awful.

Also, I can't be the only one who can single out Electron/CEF apps just from how bad the input delay is. It gives me the feeling of it being made of cheap plastic.
