Currently, this isn't a feature of the native CC support in Hubitat. but Cast-web, which was originally developed for SmartThings, and has been ported over to Hubitat works well enough to get it on your dashboards.
The native CC support beware: non-strictly technical terms ahead isn't implemented as a music player device type, so instead of following that template and passing every possible attribute and control through, it is basically just a custom multi-variable device type which contains a subset of them. In short, it's a bit stripped down, and if it were implemented as a music player currently, too many of the features wouldn't work, and it would be confusing.
(People would be clicking the skip track button and posting questions about why doesn't it work, etc.)
Cast-Web is a pretty neat API/app/device that brings a lot of the features you're looking for, if you're not familiar with it.
Cast-web can be found here, on Hubitat, and it's a bit of a rabbit hole (you have to have a separate server, for which many people use a raspberry pi or an old PC. I use a container running on a QNAP NAS I already had). But if you decide to give it a try, there are quite a few of us using it, and we should be able to help you out.
Like you, I have dashboards in rooms that I like to have music status, playback controls, volume controls, etc. integrated into. FOR ME...the point of home automation is to tie in the things I want my house to do, and control it all seamlessly from the most convenient places in my house, and for me that includes full featured dashboards. I'm glad I don't leave it up to someone else to tell me what my home automation system is for.
I'm running Sharptools as my dashboards because I'm a tinkerer for fun and a designer for work, but I also maintain built-in Hubitat dashes for quick pocket control.
Here's a small thread about getting these features where I wanted them, which just led to me continuing with the use of my already-running cast-web from ST days. As you can see, there is active discussion about getting these features going, and it's come up as a topic a few times before.
Hopefully any of that is helpful to at least get up to speed with the state of things. If we're not attempting to help each other figure out what makes our experience better, what are we doing here, right?
