Jupyterhub hosted remotely on server - FileChooser() Select file from local machine

I have hosted jupyterhub on a remote server. A model is created were I need to pass the input file as a CSV. To run the model I am using file= FileChooser() to select the file.

This works when running the model locally from my PC but when hosted on a server, How to pass enable to select the file from local drive rather from the server were jupyter is hosted.

Any pointers please
