Thanks both. I disliked both the 3P and the flatpak standalone wrappers. All they did was launch/interact with the browser. So one app morphs into two open apps. No good for me.
I'm preferring the web app.
This is exact opposite of my Zoom experience: love the standalone wrapper, loathe the web app. But they worked independent of each other.
Everyone's taste is different, for sure.
Sticking with web app---please mark SOLVED, thanks.
