Advanced Camera Card with Frigate and Grid

Does anyone know how to setup the advanced camera card to get a grid (2 x 2) of cameras that uses the Frigate cameras?

I can pull in single Frigate Camera, but I can’t seem to figure out how to set that up with a grid. What do I need to change here?

      - type: custom:advanced-camera-card
        cameras:
          - frigate:
              camera_name: scrypted_ring_door_bell
              camera_name: scrypted_ring_living_room
            live_provider: go2rtc
            display:
              mode: grid
