Automatically load data into ParaView Glance?

I have a similar question. Suppose that I have a html document with an iframe pointing to ParaView Glance:

<iframe src="https://kitware.github.io/paraview-glance/app" id="iframe"></iframe>

(How) Can I upload data in the html document via using that iframe? Will this have the same restrictions as mentioned above or can I upload local data this way?
