-var bundle = {
-    bundle: "bundleName1",
-}
-Notification.isNotificationEnabled(bundle).then((data) => {

-});
-```
-
-If the check result is **false**, notification is disabled. In this case, enable it.
-
-```js
-var bundle = {
-    bundle: "bundleName1",
-}
-Notification.enableNotification(bundle, true, async(err) => {
-    console.log("===>enableNotification success===>");
-});
