MDX over the default Markdown kernel

[ken-okabe]

Taking advantage of remark-mdx, I want to use MDX over the default Markdown kernel of .NET Interactive Notebooks extension for Visual Studio Code

I've been looking for the information all day, but could not find the appropriate information for me, so I would like to ask here.

As far as I know,

https://code.visualstudio.com/api/extension-guides/notebook

Parts of a Notebook#
A notebook consists of a sequence of cells and their outputs. The cells of a notebook can be either Markdown cells or code cells, and are rendered within the core of VS Code.

Probably it would be possible to implement MDX as the {code} and show the output, but I want to optionally replace ##Markdown with ##MDX.

Is this possible? If possible please let me know which documentation I should investigate. Thank you.
