Fine tuning modern style template sensor - a little help needed

Configuration
9

This won’t provide exactly what you want but I am posting it here for future reference. The result of this will be sensor.template_track_darren_desktop whose friendly_name is “Darren’s Desktop” (assuming I configured the quotes correctly).

template:
  - sensor:
      - unique_id: track_darren_desktop
        state: "{{ 'Connected' if is_state('device_tracker.darren_desktop', 'home') else '------------------' }}"
        icon: "{{ 'mdi:desktop-classic' if is_state('device_tracker.darren_desktop', 'home') else 'mdi:lan-disconnect' }}"
        attributes:
          friendly_name: "{{ 'Darren''s Desktop' }}"
