Why icons aren't showed?

Wonder why icons aren’t shown properly in the Companion App or in the Apple Watch … what I am missing here?

This is my setup:

actions:
  - name: SetupOffice
    background_color: "#000000"
    label:
      text: "Setup Office"
      color: "#ff0000"
    icon:
      icon: office-chair
      color: "#ffffff"
  - name: TurnOnLivingRoomTv
    background_color: "#000000"
    label:
      text: "Turn On Tv"
      color: "#ff0000"
    icon:
      icon: tv
      color: "#ffffff"
  - name: TurnOffKidRoom
    background_color: "#000000"
    label:
      text: "Turn Off All Devices at Kids Room"
      color: "#ff0000"
    icon:
      icon: child-toy
      color: "#ffffff"
  - name: BedTime
    background_color: "#000000"
    label:
      text: "Prepare Home for Bedtime"
      color: "#ff0000"
    icon:
      icon: bed-time
      color: "#ffffff"

And this is what I see in the app (same in the watch):
