• Head over to your Adalo dashboard.
• Pick the app where you want to set up user notifications.

• Go to the "Database" section.
• Create a new collection called "Notifications".
• Add properties like "Title", "Message", "User", "Read", etc.

• In the "Notifications" collection, add a relationship property to link each notification to a user.
• Make sure the relationship is "Many to One", so many notifications can belong to one user.

• Figure out what action will trigger a notification (e.g., a new message, a status update).
• Go to the screen where this action happens.
• Use an action that updates the "Notifications" collection when the trigger event occurs.

• Go to the Adalo screen where you want to show notifications.
• Drag and drop a "List" component.
• Bind the list to the "Notifications" collection.
• Customize the list items to show properties like "Title" and "Message".

• Set a filter on the notification list so it only shows notifications for the logged-in user.
• Use a condition like "Current Notification's User is equal to Logged-in User".

• Add a button or another interactive component to each notification item in the list.
• Set an action for this component to update the notification’s "Read" status to true.
• Or, create a separate screen for detailed notification view with an automatic "Read" status update.

• For real-time notifications, think about integrating external services like Pusher or Firebase.
• Set up these services to notify or refresh data in the Adalo app when new notifications are created.

• Test the notification system by performing trigger actions within your app.
• Check that the notifications show up correctly for the intended users and that they update properly.

• Once testing is done, publish your Adalo app.
• Make sure users can receive and interact with notifications as intended.

Following these steps should give you a fully functional user notification system within an Adalo app.
