Directly return an HTML file to load

[RSS1102]

I used an MD API that can convert MD strings into HTML elements.
I want to use him to manipulate the MD string, what should I do?

---

1. I tried using the vite plugin to intercept the received MD string for conversion, but it seems that even after the return, it still needs to be marked down and parsed again.Is there a way for me to directly have vitepress load an HTML elements?
   in vite plugin

import { Plugin } from 'vite'
import { default as CherryEngine } from 'cherry-markdown/dist/cherry-markdown.engine.core.common';


const cherryEngineInstance = new CherryEngine({});
export default function vitePluginVitepressCherryMarkdown(): Plugin {
  return {
    name: 'vite-plugin-vitepress-cherry-markdown',
    transform(code, id) {
      const matchFiles = Array.from(id.matchAll(/\.md/g));
      const indexFiles = Array.from(id.matchAll(/index.md/g));
      if (!matchFiles.length || indexFiles.length) return;
      //The returned string is an HTML element string
      return cherryEngineInstance.makeHtml(code);
    },
  }
}

2. I tried using its function but it still doesn't work,
   in .vitepress/config.js

  async transformHtml(code, id, context) {
    const matchFiles = Array.from(id.matchAll(/\.md/g));
    const indexFiles = Array.from(id.matchAll(/index.md/g));
    if (!matchFiles.length || indexFiles.length) return;
    return cherryEngineInstance.makeHtml(code);
  },
