How to stop sending notification?

Hi, I am learning HA. I started from sending notification via pushbullet. Below is a part of my code.

I tried to send a sample url to myself every 1 minute after 10:10 am until I click the url. So far I learned the part that I send the notification every 1 minute but I don’t know how to stop sending after I open the url that the notification sent me.

automation:
- alias: 'Notify Me after 10:10 am'
  trigger:
    platform: time
    after: "10:10:00"
    minutes: '/1'
    seconds: 00
  action:
    service: notify.paulus
    data:
      title: Send URL
      message: This is google.com, click it! The sun is {% if is_state('sun.sun', 'above_horizon') %}up{% else %}down{% endif %}!
      data:
        url: google.com

Please help this beginner! :frowning:

Thanks!

There is no way of telling HA that you have clicked the URL. You should look at the alert component that allows you to acknowledge.
