Embed a Jupyter Book into an existing sphinx project documentation

[HealthyPear]

Hello,

I am using pydata sphinx theme to document a python package containing a notebook library.

Within the main documentation, I would like to build a Jupyter book based on these notebooks and embed it as one of the
top-level pages of my document (so from the toctree of the main index.rst).

I manage to compile the jupyter book separately, but then I don't know how to add it to my documentation.

I tried to use jupyter-book config sphinx and add from ..conf import * into the "child" sphinx configuration, but then I see only the HTML equivalent of intro.md without the notebook "pages"
