How do I obtain the unified instance (or, list of plugins to reproduce the unified instance) used by nuxt content?

Question

I am using Nuxt Content (v1).

As explained in the doc, internally, this library uses remark and rehype, for parsing and converting markdown file to html AST. https://content.nuxtjs.org/configuration

Now, I have a string which I'd like to parse and transform using the unified instance which Nuxt Content uses. Example usecase is to parse string defined in front-matter as an markdown, so that e.g. following can be parsed and turned into html the same way as in markdown content.

description: "About `export { default } from 'lib'` statement."
desiredDescription: "About <code>export { default } from 'lib'</code> statement."

Although "using same unified parse/convert logic" can be achieved by manually listing all the plugins by oneself and using it by e.g. remarkPlugins: () => listOfAllRemarkPlugins in nuxt.config.js, since Nuxt Content comes with handy default plugins and its configurations, I would want to rather reuse them, not handling all the plugins manually by myself.

So question: Can I obtain the unified instance, or list of plugins and its options, used by Nuxt Content so that I can do the same transformation against markdown strings as Nuxt Content does against markdown file contents?
