I'm writing an extension for Flarum to add a notification feature when a new transaction is created. On the backend, I've registered the NotificationBlueprint and NotificationSerializer correctly in the extend.php file as per the documentation, but the notification still doesn't appear on the frontend.
I've checked the following:
Registered the notification component in js/dist/forum.js with app.notificationComponents.
The notification sending part using NotificationSyncer has been called correctly.
The notifications table in the database records the notification.
However, the notification is still not showing on the forum interface.
