There is more and more requests to add new notifications to Notification extension. We need to change how they are explained on documentation to make easier a new addition, translate it or have an overview of the different notifications.
Leads:
- separate "core" Notifications from Notifications generated by extensions (Newsletter, Flow...)
- improve explainations about how they are displayed (Alerts vs Messages) or actions that may be needed
- Improve information about what will be the possible actions after people click on the notification
- Define a template or some document about how to add a new notification to documentation
