Browser mod pop up empty

Hello,

I am trying to create a button that, when pressed, opens a card with multiple cards (blind controls).
My current attempt is this:

show_name: true
show_icon: true
type: button
tap_action:
  action: fire-dom-event
  browser_mod:
    service: browser_mod.popup
    deviceID: this
    data:
      type: entities
      entities:
        - cover.blinds_entrance
entity: person.akio_w_wauer

When I press the button, a pop up opens… but it seems to be empty:

Any ideas?
Thanks.

I think you’ll need to add the correct browser ID, not this ?

try this in capitals THIS

I got it to work:

show_name: true
show_icon: true
type: button
tap_action:
  action: fire-dom-event
  browser_mod:
    service: browser_mod.popup
    data:
      dismissable: true
      autoclose: false
      title: Test
      content:
        type: entities
        entities:
          - cover.blinds_entrance
          - cover.blinds_lunch
          - cover.blinds_kitchen
      right_button: All UP
      left_button: All DOWN
      right_button_action:
        service: cover.open_cover
        data:
          entity_id:
            - cover.blinds_entrance
            - cover.blinds_lunch
            - cover.blinds_kitchen
      left_button_action:
        service: cover.close_cover
        data:
          entity_id:
            - cover.blinds_entrance
            - cover.blinds_lunch
            - cover.blinds_kitchen
entity: person.akio_w_wauer
