Entity Filter Card perfect except no secondary info

My two favorite functions on the front end are the Entity Filter Card and the Entities secondary_info: last-changed option.

But they don’t work together. Both are great and when I see a entity turned on and visible I wonder why I don’t see the last-changed info :frowning: then I remember they don’t work together.

type: conditional
conditions:
  - entity: input_boolean.test_toggle
    secondary_info: last-changed    # wish this worked :(
    name: dontworkeither
    state: 'on'
card:
  show_name: true
  show_icon: true
  type: button
  tap_action:
    action: toggle
  entity: input_boolean.test_toggle
