Determine last called HomePod

Configuration
1

I am moving away from Alexa to HomePod. In the Alexa integration there was a “last called” sensor that could be used to determine which Alexa was used to fire the event/automation in HA. I’ve been trying to find a similar way to do the same with HomePod without good results. I’ve tried a few examples via ChatGPT, but the HomePods don’t seem to update “playing” when called as the script assumes. Is there a way to send which HomePod is sending the command to HA? Perhaps through a variable in Shortcuts?

- platform: template
  sensors:
    last_called_homepod_name:
      friendly_name: "Last Called HomePod"
      value_template: >
        {% set homepods = states.media_player
          | selectattr('entity_id', 'search', 'media_player.homepod')
          | selectattr('state', 'eq', 'playing')
          | sort(attribute='last_changed', reverse=True)
          | list %}

        {% if homepods | length > 0 %}
          {{ homepods[0].name }}
        {% else %}
          Unknown
        {% endif %}
