trouble specifying options with @next/mdx

[dingran]

According to the read me, all options would be passed to MathJax, so I thought I'd just specify them as usual

{
          tex: {
            inlineMath: [
              ['$', '$'],
              ['\\(', '\\)'],
            ],
            tags: 'ams',
          },
          svg: {
            fontCache: 'global',
          },
}

Here is how next.config.js looks like

const mathJax = require('rehype-mathjax');

const withMDX = require('@next/mdx')({
  extension: /\.mdx?$/,
  options: {
    remarkPlugins: [require('remark-math')],
    rehypePlugins: [
      [
        mathJax,
        {
          tex: {
            inlineMath: [
              ['$', '$'],
              ['\\(', '\\)'],
            ],
            tags: 'ams',
          },
          svg: {
            fontCache: 'global',
          },
        },
      ],
    ],
  },
});
module.exports = withMDX({
  pageExtensions: ['js', 'jsx', 'md', 'mdx'],
});

However, I got the following error

./pages/test.mdx Error: Invalid option "tex" (no default value). at Array.forEach (<anonymous>)

Wondering if I misunderstood how to set options? Thanks!
