StatusNotification has attributes called appId and appControl along with other useful attributes.

https://developer.tizen.org/development/api-references/web-application?redirect=/dev-guide/latest/org.tizen.web.apireference/html/device_api/wearable/tizen/notification.html#StatusNotification

appId attribute can be used to launch an application with it's application Id.

appControl attribute can be used to launch an application control operation.

Sample app launch using appId with notification code snippet:

var myappId = tizen.application.getAppInfo().id;    // The app posting the notification 
var otherAppId = "org.tizen.clocksetting ";        //'settings' appId for example

var notificationDict =
   {
      content: "Notification App Launch",
      vibration: true,
      appId: myappId             // or otherAppId
   };

var notification = new tizen.StatusNotification("SIMPLE", "Simple notification", notificationDict);
tizen.notification.post(notification);

For more advanced appControl you can check these Guides:

You are not going wrong here. My finding is such problem occurs in Tizen Emulators only, When you deploy the app to real Gear Device it works just fine.

AppId or AppControl is not working in Emulators.

Screenshot of notification on my GearS3 device:

But for Wearable Emulator, the Screenshot is same as your's for the same notification.
