Breaking changes for dismissOnPageChange should propose a viable alternative

What is missing or inaccurate about the content on this page?
The doc says that as a workaround for the removed dismissOnPageChange, there are global events (ionNavWillChange, ionNavDidChange) that you can listen to in order to detect when navigation occurs.

I can't find any documentation anywhere on how to actually use ionNavDidChange, so this is not a great proposed alternative.

I managed to get it working using this code in app.component.ts to subscribe to Angular router events:

router.events.subscribe(event => {
  if (event instanceof NavigationEnd) {
    // Do something
  }
});

Perhaps this should be documented as an alternative to dismissOnPageChange.
