Shark IQ Vacuum Integration

Hi, could it be that the integration isn’t working correctly? According to the documentation, the following action should work:

action: sharkiq.clean_room
data:
  rooms:
    - "Eingang"
target:
  entity_id: vacuum.robi

However, nothing happens, or rather, it tells me the room name can’t be found. But the room name is 100% correct.
