Send notification from one page to another

HI!

I’m finishing my login and registration structure, so I’ve wanted to send a notification from de “Change Password” page to my Login page when the password has been successfully updated by the user.

I’ve already tried using the on Success… go to login and adding a query parameter to the login page. But I can’t find any conditional for the login page that checks if there is any parameter in the URL and runs the notification.

Thanks!
