How to use the y-websocket.WebsocketProvider function in y-websocket

import * as Y from 'yjs'
import { WebsocketProvider } from 'y-websocket'
import { prosemirrorPlugin, cursorPlugin } from 'y-prosemirror'

import * as conf from './exampleConfig.js'

import { EditorState } from 'prosemirror-state'
import { EditorView } from 'prosemirror-view'
import { DOMParser } from 'prosemirror-model'
import { schema } from './prosemirror-schema.js'
import { exampleSetup } from 'prosemirror-example-setup'
// import { noteHistoryPlugin } from './prosemirror-history.js'

const provider = new WebsocketProvider(conf.serverAddress)
const ydocument = provider.get('prosemirror' /*, { gc: false } */)
const type = ydocument.get('prosemirror', Y.XmlFragment)

const prosemirrorView = new EditorView(document.querySelector('#editor'), {
  state: EditorState.create({
    doc: DOMParser.fromSchema(schema).parse(document.querySelector('#content')),
    plugins: exampleSetup({ schema }).concat([prosemirrorPlugin(type), cursorPlugin])
  })
})

const connectBtn = document.querySelector('.y-connect-btn')
connectBtn.addEventListener('click', () => {

    ydocument.disconnect()
    connectBtn.textContent = 'Connect'
  } else {

import * as Y from '../src/index.js'
import { WebsocketProvider } from 'y-websocket'
import { QuillBinding } from 'y-quill'

import * as conf from './exampleConfig.js'

import Quill from 'quill'

const provider = new WebsocketProvider(conf.serverAddress)
const ydocument = provider.get('quill')
const ytext = ydocument.define('quill', Y.Text)

const quill = new Quill('#quill-container', {
  modules: {
    toolbar: [
      [{ header: [1, 2, false] }],
      ['bold', 'italic', 'underline'],
      ['image', 'code-block'],

const ydocument = provider.get('dom')
const type = ydocument.define('xml', Y.XmlFragment)
const binding = new DomBinding(type, document.querySelector('#content'), { scrollingElement: document.scrollingElement })

window.example = {
  provider, ydocument, type, binding
}
