I see. I tried the following and it worked:

(with-eval-after-load 'ox-html
  (add-to-list 'org-html-mathjax-options
               '(path 
"https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js";)))

The "export" blocks did not work for me, but the following did:

(setq-default org-html-head "
  <script>
  window.MathJax = {
    loader: {load: ['[tex]/mathtools']},
    tex: {packages: {'[+]': ['mathtools']}}
  };
  </script>")

All the above makes using MathJax extensions impractical. I would have to 
include HTML hacks in my Org documents or tie the documents to my Emacs 
configuration, if I understand everything. Neither sounds right, and thus I 
will avoid using "modern" MathJax until Org switches to it and HTML_MATHJAX 
actually works.

P.S. I wonder why Org uses MathJax 2.x when other popular tools, such as 
Pandoc, use the latest one.

Thank you for your help!
