How to embed internally-generated HTMLs into Jupyter notebook

Is your feature request related to a problem? Please describe. I’ve generated some HTML plots using Plotly, e.g. my-plot.html. Each of these plots are stored in a separate folder so that my structure looks like this

folder-to-book
└── notebook.ipynb
└── plots
    └── my-plot.html
    └── another-plot.html

I have already set this in my _config.yml:

sphinx:
  config:
    html_extra_path: ['plots']

However, if I have a cell in the notebook (in Markdown syntax) such as

* [reference to plot](./plots/my-plot.html)

OR

* [reference to plot](./my-plot.html)

Neither seem to be recognised by myST:

... WARNING: 'myst' reference target not found: my-plot.html

The closest pieces of docs that I’ve found that address this issue are:

• FAQ
• Cheat sheet

Describe the solution you’d like

All these docs are focussed on adding external HTML references as opposed to internal HTML files. Can someone please point me to there or add a tip on how this can be done?

Thank you!!

I think Yeh the main thing here is that the use of html_extra_path , is not really its intended purpose: “A list of paths that contain extra files not directly related to the documentation”, i.e. you can’t link to them or have any other sphinx integration

I could do that when I get the feeling the Jupyter Book is a viable option for my collection of notebooks. Still encountering potential show stoppers.
