Unfortunately this is not here because of Google rules
By adding this feature it opens the users to all the radios of the world directly browsable from the app including explicit radios. This is no more their own content only.
That force me to change the app content declaration and the app can no more be all public but at the very minimum teen (if I include a way for users to report too explicit radios and offer a global way to remove stations) else could even be a mature rating.
Since this would impact discoverability in Play Store that is already really hard, I can’t for the moment.
But you can just copy paste the information in the app, a lot less convenient but vital for now for the app to keep existing.
