[Feature or Configuration Suggestion?] Buttons following existing theme for other services during onboarding

[jarjarfinks]

I'd like to add buttons for other services I host in my homelab for the onboarding process. I can't see anything in the docs about doing something like this. Can I just reference a CSS class in custom HTML markdown for a button? Or does it need to be added as a feature? If I need to add CSS to make it work, what class and can you give me an example of how I might do so?

Following this. It would be awesome!
