based on given example, is it possible to have an event which will fire when saveAs() done?

In my project there was a some data fetch from API, and it was take some time. So UI is design to show "Preparing data to be exported" Loading popup. need to catch the moment when saveAs() completed to hide the loading.
Note that beside the request/response html file preparation and exportation also takes some time. So the opup must be closed right when saveAs() done
