How can I upload local files to paraview glance through post/get request?

Thanks for answer.

Does ‘client base’ means if I go to https://kitware.github.io/paraview-glance/app/ and open my local file.
the file never uploaded but stays in my computer and browser do the work?
So no get or post request ever happened after the page loaded?

I guess I just follow this answer

Thanks a lot.
