[Feature request] Integration in "notifications and messaging tray"

[7system7]

Firstly, I would like to thank you for your work. It is a great app, it should be a part by-default the GNOME.

Description

Actually, I have 3 idea

1. It would be good, if there is an option that can integrate this app to the messaging tray, below the mini-calendar, for example.
   
2. The text is too long, (on the panel) and it is not changeable. For example, I think, it is enough to view the remaining time in this format: "3:10 | <title>" Or it would be nice, I can see only one icon. Maybe the best option is to define the format of the message on the panel, like this:
   
3. The default application should be changeable. For example w/ Zoom link, it does not matter, which browser will open it, cause' it has a dedicated desktop app. Google Meet is not. I use Firefox for almost everything, but, i.e.: the Meet does not support the background visual effects. So, I use it in Chromium. (And I’m probably not alone with my decision.)

Hey, i'd love to support the panel notification but this would mean rewriting this as a vala/javascript extension which goes beyond my skills..

The multipe browser support make a lot of sense, we just need a UI for configuration to be able to do it properly.

I currently use a wrapper script that switch browser on url (ie: https://meet.google.com/* to open on chrome and other in firefox)
