How do I display count in lovelace using decluttering card

I have a sensor counting my lamps that are on.
However i want to show it using a conditional card.
This card works, but now i want to see the amount of lamps in it? How should i do this?

- type: conditional
    - entity: sensor.current_lights_on
      state_not: "0"
    type: custom:decluttering-card
    template: notification_template
      - name:  lampen aan

Now its just showing “lampen aan”

Anyone want to put me on the right way?

Late to the party - but I am using GitHub - thomasloven/lovelace-auto-entities: 🔹Automatically populate the entities-list of lovelace cards for a similar case.
