Can you clarify what you mean by the radio station icon? Are you referring to one of the 1x1 tiles? (eg. rmf maxxx)?
A common approach is to use a Media Tile and then use the Hyperlink Action to run your desired rule to start your station playing.
@James has an example of this in his Create "Jukebox" Dashboard with Album Art for Echo or Sonos Devices thread:
If you’re referring to the Album Art tile in the top-left corner of your screenshot, that depends on if the media player and the radio station exposes the relevant album art.
