 card:

      action: url
      url_path: https://github.com/dermotduffy/frigate-hass-card/releases

 #### Menu state icons
 You can add custom state icons to the menu to show the state of an entity and complete arbitrary actions.
 <details>
  <summary>Expand: Custom menu state icon</summary>
 This example adds an icon that represents the state of the
 `light.office_main_lights` entity, that toggles the light on double click.

    entity: light.office_main_lights
    tap_action:

 #### State badges
 You can adds a state badge to the card showing arbitrary entity states.
