Syntax Help in yaml

Hi! I am trying to add multiple services to an automation in my weatheralerts.yaml

I am not great with syntax so I’m not sure if it should be:

      - service: and
        - notify.mobile_app_cjs_iphone
        - notify.modile_app_lindsays_iphone_2
        - notify.modile_app_davin_s_iphone

Or something else? Originally I had it as:

      - service: notify.mobile_app_cjs_iphone

which obviously worked fine but now that I want to send the info to my wife and son the weather seems to be fine and I am not sure how to really test it either. Thanks for any and all help!

You need to make a notification group I yaml using the group integration.
