How to use the @marp-team/marp-core.Marp function in @marp-team/marp-core

md.parse = (markdown: string, env: any) => {
    // Generate tokens by Marp if enabled
    if (detectMarpFromMarkdown(markdown)) {
      const mdFolder = Uri.parse(md.normalizeLink('.')).with({ scheme: 'file' })
      const workspaceFolder = workspace.getWorkspaceFolder(mdFolder)
      const baseFolder = workspaceFolder ? workspaceFolder.uri : mdFolder

      const marp = new Marp(marpCoreOptionForPreview(md.options))
        .use(customTheme)
        .use(outline)
        .use(lineNumber)

      // Load custom themes
      let shouldRefresh = false

      Promise.all(
        themes.loadStyles(baseFolder).map(promise =>
          promise
            .then(theme => {
              if (theme.registered) shouldRefresh = true
            })
            .catch(e => console.error(e))
        )
      ).then(() => {

module.exports = opts => {
  return new Marp(opts)
    .use(markdownItMark)
    // .use(markdownItFootnote)
    .use(markdownItAbbr)
    .use(markdownItSup)
    .use(markdownItSub)
    .use(markdownItEmoji)
    .use(html5Media)
    .use(markdownItContainer, 'note');

}

export const Marp = props => {
  const marp = new MarpCore({
    container: null,
    script: false,
    printable: false,
  })

  marp.markdown.normalizeLink = url => resolvePath(url)

  const rendered = marp.render(props.markdown, { htmlAsArray: true })

  return (
    <div>
      </div>
