title: Can't create a class from module in React
body: <p>my purpose to create a collaborative editor with Monaco editor and Convergence. I'm following these repo and example:</p>
  <p><a href="https://github.com/convergencelabs/monaco-collab-ext" rel="nofollow noreferrer">https://github.com/convergencelabs/monaco-collab-ext</a>
  <a href="https://github.com/convergencelabs/javascript-examples/blob/master/src/examples/monaco/monaco-adapter.js" rel="nofollow noreferrer">https://github.com/convergencelabs/javascript-examples/blob/master/src/examples/monaco/monaco-adapter.js</a></p>
  <p>I just import this module</p>
  <pre class="lang-js prettyprint-override"><code>import MonacoCollabExt from '@convergencelabs/monaco-collab-ext';
  </code></pre>
  <p>Then I try to create a new object from a class of this module</p>
  <pre class="lang-js prettyprint-override"><code>        const contentManger = new MonacoCollabExt.EditorContentManager({
            editor: editor,
            onInsert(index, text) {
              _model.insert(index, text);
            },
            remoteSourceId: 'convergence',
          });
  </code></pre>
  <p>But I got an error <code>&quot;Cannot read property 'EditorContentManager' of undefined&quot;</code> Seem like MonacoCollabExt is undefined, but I already install it as dependencies and imported it. What is wrong? Thanks!</p>
