Call popup on page close?

Question

JavaScript

I want to implement just such a thing: when a user wants to leave the page, I need a pop-up with a questionnaire to pop up. Tell me how can this be done? Did I understand correctly that this cannot be done through the beforeunload event? If not, then how, maybe someone had experience of something similar.
It would be ideal if someone suggested something like this

The easiest option:

$(document).mouseleave(function(){$('#leaveModal').show();});
