@chapoi thanks for the response. I’m curious: are you planning to use the standard browser Notification API? This works well across all my browsers these days, and ironically, it works in Discourse for example when I send a private message (at least on desktop but not on Android). Are there particular browsers or platforms where the chat works as expected? There are clearly preferences about audible chimes and push notifications, so it must be working for somebody. If you can point me to the relevant git branch perhaps I could contribute to the effort.
