A way to add buttons and renaming "Jellyfin"

I'd love a button that links to my instance, and a way to rename the "Jellyfin" name to my instance name.

I made a horrible picture to better ilustrate what I mean:

BTW love your work ❤️

So first of all to change the "Jellyfin" name, you need to make an app on discords developer page with the name you want and then replace the application ID in the config.

Second of all I'll look into making custom buttons a thing
