[_config.yml & mathjax] How to use mathjax Tex/Latex Extension ?

[rla523at]

I am making .html in .md using Jupyterbook.

However, the problem is that some macros ('\mathclap, \Set'...) are not rendered properly in the .html file.

I saw here(MathJax Supported TeX/LaTeX commands), that some macros are defined separately in extensions such as amscd, braket, and mathtools.

So I looked up how to load the extension in here(TeX and LaTeX extensions & autoload) and tried to apply it.

I think I need to modify _config.yml, but I don't know how to.

In my _config.yml, the part related to MathJax is written as follows.

  config:
