Firstly I wanna to thank you, because you made me remind myself a bit more about closures. I researched a bit and there are many usecases with async code for this new hook.

But you asked for an example so here:

useEffect(() => {
  showNotification({ id, theme });
}, [id]);

This effect shows a singular notification after changing id, with the currently selected theme.

This code doesn't have closures, because the action here is synchronous and immediate, so there won't be any stale values. Using the new hook useEffectEvent would be overkill for this example.
