How to syntax highlight MDX in CodeMirror v6?

I saw How to use GFM mode in codemrror6 - #2 by fabianmichael but it doesn’t show how to do JSX highlighting inline in Markdown, ala MDX. Does CodeMirror v6 have support for MDX syntax highlighting? If so, how can you accomplish this? If not, what would it take for me to add support?

Thank you very much!
