About 2 years after Google switched every Google Hangouts user over to Google Chat, I still wonder about [Wayback/Archive] Will the new Google Chat PWA for Chrome ever have system tray support? : gsuite:
Chrome _right now_ can be sustained as a background process with the Chrome-ball in the system tray. This is the vehicle with which Hangouts remains open at all time, so why not Chat, too?
I’m left with no option but to have Chat running on a mobile device so I have always on access. Perhaps this is the angle. I nunno.
Your support page link I’ve seen already and it doesn’t answer the Why question.
It is absolutely a bizzarotown implementation.
