Custom Plugins don't work in vue viewer while they work in vue editor

[zifnab87]

Describe the bug

custom Plugins (e.g youtubePlugin example) don't work in viewer while they work in editor. Imported chart plugin works fine in both editor and viewer

To Reproduce

Expected behavior

Viewer should show youtube video as well as chart - it only shows chart and not custom plugin youtube

Screenshots

editor:

fixed by using this setup from #899 (comment) :

working:

youTubePlugin(editor) {
      const { codeBlockManager } = Object.getPrototypeOf(editor).constructor
      codeBlockManager.setReplacer("youtube", youtubeId => {
         [...]
        return `<div id="${wrapperId}"></div>`;
      });
    }

not working:

import TuiEditor from '@toast-ui/editor'
youTubePlugin() {
    TuiEditor.codeBlockManager.setReplacer('youtube', (youtubeId) => {
        [...]
        return `<div id="${wrapperId}"></div>`
    })
},

Please update your documentation! Thanks :)
