Button state to indicate which radio station is selected

[uncappedshady]

Hi there, I have created a mini-media-player card with buttons for radio stations. What I cannot seem to get working is to have the button highlighted that I selected to indicate which radio station is currently playing.

Any ideas on how to achieve this?

Below is my code:

type: custom:mini-media-player entity: media_player.googlehome0339 shortcuts: buttons:

• id: https://live.jacarandafm.com/jacarandahigh.mp3 image: http://cdn-profiles.tunein.com/s6410/images/logod.jpg name: Jacaranda FM type: music
• id: >- https://playerservices.streamtheworld.com/api/livestream-redirect/FM947.mp3 image: https://cdn-radiotime-logos.tunein.com/s6400d.png name: 94.7 FM type: music

And here is the card:
