Group of cameras not showing up?

Hello,

I created a group of my cameras :

group_binnencameras:
  name: group_binnencameras
  entities:
    - camera.fi9826p_living
    - camera.fi9826p_gang

I have this script :

alias: Bewegingsdetectie binnencamera's inschakelen
sequence:
  - service: camera.enable_motion_detection
    target:
      entity_id:
        - camera.fi9826p_living
        - camera.fi9826p_gang
    data: {}
mode: single

How can I now use this group (instead of the individual cameras), cause the group is not showing up on the UI ?

Nobody to help me ?
