Roon - How to use Playlists?

Configuration
1

So I have a Roon server on the network and everything works well when using media_player.play_media to play songs, albums and artists.
But I cant for the life of me figure out how to play a playlist. I have been banging my head against this for weeks now. I have been through the forums, nothing helped.
Can someone please take pity on me?
What do I set as content ID and what do I use for content type?

Did you try this?

  • To start a playlist, set the name of the playlist as the “media_content_id” and set “media_content_type” to “playlist”.

I have just tried it. I can’t get it to work
My code:

action: media_player.play_media
metadata: {}
data:
  media_content_id: "Samurai"
  media_content_type: "playlist"
target:
  entity_id: media_player.gaincell_dac
