Exporting JupyterLite notebook site rooted on ./index.html

[psychemedia]

The current build (using the XML formatter) generates an element of the form:

 <NotebookLiteIframe height="600px" iframe_src="lite/tree/" prompt="Try classic Notebook!" prompt_color="True" search_params="false" width="100%">

where the the iframe_src points to the path lite/tree/ which in turn loads assests from the parent dir...

Is it possible to generate a "flat" distribution rooted on ./index.html?

I have a requirement of bundling the site as an html.zip file where the entry point MUST be ./index.html, rather than anything down a path.
