Is that this channel? (See attached screenshot) …if so, it’s available via the MyTuner Radio Service in the Sonos App or you can just add the radio station URL as mentioned here:

Thank you Ken for your quick anwser.Its  not the station on the picture you post  , unfortunatly

I tried addind the channel following the method in the link but sonos sent an error coding message , this station has no official Website but is host on streaming website . Luckily it as its own app on ion and android . 
 

Best regards

If they have a login for their app, and their webpage, you wouldn’t be able to add it natively to Sonos. Assuming you have the correct controller device (iOS or MacOS) and the appropriate Sonos speaker, you could use AirPlay 2 to send the signal to the Sonos system.

Sonos doesn’t control who gets added to their system, they can’t legally go grab any stream. Each streaming system chooses to join the Sonos ecosystem. You may want to point these folks at the Sonos partners page, where they can find details about how to join Sonos. 

Thank you very much Bruce for your answer
