feed a variable to the option image

[guaro2k]

I've tried a bunch of code to be able to feed the option image a variable instead of a url path

its supposed to be be like this:

image: "image/path"

I have a template variable that saves the changing url for the media for Sonos

sensor.sonos_media

with a state :
/api/media_player_proxy/media_player.living_room?token=1124256fa1cae8e1be0c476c2ce881aaf523ff4cfeaba2b1866759033a944f8b&cache=d05f973fec3e2c7b

The token changes every time there is a new image cover

How do I do image: sensor.sonos_media????
