 ### Publishing Notifications
 
-Before publishing a notification, make sure the notification feature is enabled for your application. This feature is disabled by default and can be enabled in the notification settings.
+##### Enabling Notification
+
+Before publishing a notification, check whether the notification feature is enabled for your application. By default, the feature is disabled. The application calls **Notification.requestEnableNotification** to prompt the user to enable the feature.
+
+```js
+Notification.requestEnableNotification() .then((data) => {
+	console.info('===>requestEnableNotification success');
+}).catch((err) => {
+	console.error('===>requestEnableNotification failed because ' + JSON.stringify(err));
+});
+```
+
+
 
 ##### Publishing Notifications
 
 To publish a notification, create a **NotificationRequest** object and set attributes such as the notification type, title, and content. In the following examples, a normal text notification and a notification containing a **WantAgent** are being published.
