Voila output to html - can't see output file

Question

This is a simple query about the useful voila module in python

I've got a jupyter notebook called voila_testing.ipynb - although it could be any notebook.

It is hosted on Sharepoint and all I want to do is is output the voila results into an html file as not too many people can access the jupyter notebook on our system.

I've tried running it and then using the command line in vscode to run

voila voila_testing.ipynb --template=lab --export=output.html

But although the html page comes up it doesn't generate an output.html file.

Otherwise it would be a simple solution for my dashboard work.
