Nav from AppComponent not showing Tabs

I’m using OneSignal to receive push notification. But when i send this.nav.push(NotificationsPage, {data: data}); the page open but not showing Tabs from TabsPage. What can i do?

  templateUrl: 'app.html'
export class MyApp {

  @ViewChild('myNav') nav

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen, userStorage : UserStorageService, private oneSignal: OneSignal ) {
platform.ready().then(() => {
  // Okay, so the platform is ready and our plugins are available.
  // Here you can do any higher level native things you might need.

  userStorage.isAuthenticated().then(isAuth => {

    if(isAuth) {
      this.rootPage = TabsPage;
    } else {
      this.rootPage = ChooseCompanyPage;

  this.oneSignal.startInit("XXXX", "XXXXX")


  this.oneSignal.handleNotificationOpened().subscribe(data =>{
    this.nav.push(NotificationsPage, {data: data});




I have no idea, but a hunch: Should you listen to the notification in TabsPage maybe and nav.push there?
