Trigger on Android notification

On the home assistant, I enabled the Android Last Notification sensor. However, when I go to Automations and then choose (under Triggers) my Pixel 4, I don’t see anything related to notifications…

I would like to have things happen if I receive a notification on my android (depending on the type of notification). I see a bunch of other sensors listed but nothing related to notification.

I think it’s under services.
This video will help.

Thanks, but this looks like teaching home assistant to send notifications rather than act on one it received.

It’s an entity.
Look in developer tools.
Sensor.[phone]_last_notification
You can either trigger on the state or template something
