At least for me, webapps are just 1 in a thousand tabs open in 500 browser windows (ok, I exaggerate a bit). For an app with it's own window I can just hit a shortcut and said app gets focus.

Same for me. I'm so surprised that browser makers still haven't solved this particular problem in spite of all browsers now being multi process.
use `chrome --app`
That doesn't work on macOS.
Different screen share features only work in the app. I'd use the web app if all I needed was chat, but I'm on video calls and using screen share constantly.
