How to tell org-reveal to use latex package

[yjwen]

Here is an example.

#+REVEAL_MATHJAX_URL: https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js

* Example Slide
$\braket{1 \over w}$

I am afraid there is no way to include a latex package, as org-reveal is an HTML backend. What is necessary of a latex package for exporting reveal.js slides?

For a talk, I need to use the quantum mechanics "braket" notation, which is accessible by
\usepacke{braket}.

Sadly, this does not compile in org-reveal.

In a nutshell, only with latex packages, I can display all equation I need to.

@FryeKai you can use MathJax with Org-Reveal which apparently supports the braket Commands.

@kir0ul Thanks for the advice. I suppose that this is a nice workaround. But I am really struggling to get MathJax running with org-reveal properly.
I think it's load using REVEAL_MATHJAX_URL but no idea how to modify it.
