I just noticed this under general configuration, in a fresh test installation of v0.71:
I am not able to enable it, so I can’t say much more, but does this mean that Home Assistant now has built-in push notifications?
I have previously used html5 - which is great with actionable and rich notifications, but they are a bit cumbersome to set up, and Google seems to deprecate the underlaying service, so an alternative would be great
