Lovalace filter tab based on havc state

I’m trying to make a new lovelace card using the entity filter. My goal is to visualize all the thermostat in HAVC that are heating (using hvac_action: heating)…

This is what I tried but it doesn’t work obviously:

type: entity-filter
  - entity: climate.testa_ingresso
  - "hvac_action": 'heating'
  type: entities

this are the infos I can get for every thermostat:

hvac_modes: off, heat, auto
min_temp: 5
max_temp: 35
target_temp_step: 0.5
preset_modes: off, custom, comfort, sleep, away, auto
current_temperature: 20.5
temperature: 22
hvac_action: heating
preset_mode: auto
friendly_name: Ingress
supported_features: 17
