How to listen for Notification events?

[HRankit]

I mean, I want to make sure that the message has been delivered and no error occurred and then I'd like to save that notification to the database. I've already gone through https://laravel.com/docs/11.x/notifications#notification-events but those events are not firing at all. Does any one has any idea of how to listen for these events, success/fail/sent etc. I've tried both methods using trait and facade
