IOS Action Trigger Automation

Can someone point me in the direction of triggering an existing automation using an action.

I have got an empty action on my iphone (setup in conf.yaml) just need some help with the syntax to point it toward the automation.

ios :

  actions:
    - name: Goodnight
      background_color: "#000000"
      label:
        text: "Time for bed"
        color: "#ff0000"
      icon:
        icon: earth
        color: "#ffffff"
`````
