Changing notification source domain in html5 push notifications

I’ve just started dabbling with html5 push notifications on chrome and there’s one thing that is bothering me. Whenever the notification comes through, the second line is always the (ugly) Home Assistant Cloud external URL.

Is there any way to hide/change this in the notification to something more friendly? I’ve looked in Chrome settings, google cloud project settings, and home assistant itself and can’t seem to find anything.
