Error: Element not found

[OAXP]

Hey when I try to use UserNotificationListener from @nodert-win10-19h1/windows.ui.notifications.management
I am trying to add a listener :

listener.addListener('NotificationChanged', (e) => {
    console.log(e);
  });

but I am getting this error, do you know where it's from and how I can fix it?
