How to know on the server if a requested file has been downloaded by the client

So I have a google cloud storage bucket where I am storing files for one time access for the users. Now I want to implement a logic where if a user has downloaded the file completely just once from the cloud storage the file must be deleted.

I want to know if there is a way by which I can invoke a function the server when the user has finished downloading a file which he/she has requested for?
