Current behavior
Apply await to event onAnyCloseEventFinished.toPromise() not working. The event did not fire after the modal closed.

Expected behavior
onAnyCloseEventFinished can work with async/await when transform to a promise ( .toPromise() )

What is the motivation / use case for changing the behavior?
I would like to pause other processes when open the modal and get the user input after the modal is closed
