Media_player group can't use title and thumb data

I’m having a bit of trouble with the media_player.play_media service in regard of a media_player group. My service call work perfectly with a single speaker before, but with a speaker group The extras aren’t set:

- service: media_player.play_media
  target:
    entity_id: media_player.matin # A media_player group
  data:
    media_content_id: https://.....
    media_content_type: audio/mp3
    extra:
      title: CHOM - The Spirit of Rock
      thumb: https://......
      stream_type: live

(Sorry for the incomplete links, don’t have access to the scripts.yaml)

Does anyone had any chace in setting the media data in a speaker group?
