Ui-lovelace.yaml and assumed_state

I cannot add assumed_state (the round toggle button, not 2 button) to switch in ui-lovelace.yaml.
My code is

views:
  - title: SUMMARY
    icon: mdi:home-outline
    cards:
      - type: entities
        title: Bedroom Lights
        assumed_state: false
        show_header_toggle: false
        entities:
          - entity: switch.left_gang_3
            icon: mdi:ceiling-light
          - entity: switch.right_gang_3
            icon: mdi:ceiling-light
          - entity: switch.left_gang_1
            icon: mdi:ceiling-light

Does anyone know what I missed? Thanks for helping me.

assumed state is not a possible field on entities card.

I add it to customize.yaml and worked :smiley:
