Writing calendar events using sensor output

Configuration
1

I am struggling with the following:

I use a scraper HACS Afvalwijzer which provides me sensor entities with the correct dates for waste collection. I receive the sensors and can put them in a card, etc.
I am also using the Google Calendar integration, which also works fine.

What I would like is to write an automated a calendar event in google, when a waste collection sensor comes up with a new date.

I am looking for a simple solution since I am fairly new to all this. At this moment I am trying to get it done in Settings>Automations and go from there. I am not (yet) familiar with using templates.

Could anyone get me on the right track for this?

This is what I got so far (obviously not working)

      to: ‘on’
      condition:
    • condition: template
      value_template: ‘"{{ state_attr(’‘sensor.afvalwijzer_gft’’, ‘‘date’’) == true
      }}"’
      action:
