Add Markdown Plugin to CKEditor 5 Plugin for Typescript Strapi

I tried that and it’s still not working for the markdown plugin, should the import sentences be different ?
I tried all of this (my app.tsx):

import { Markdown } from "@ckeditor/ckeditor5-markdown-gfm";
import ckeditor5Dll from "ckeditor5/build/ckeditor5-dll.js";
import ckeditor5MrkdownDll from "@ckeditor/ckeditor5-markdown-gfm/build/markdown-gfm.js";
import GeneralHtmlSupportDll from '@ckeditor/ckeditor5-html-support/build/html-support.js';

export default {
  config: {
    locales: [],
  },
  bootstrap(app) {
    console.log(app);
  },
};
