title: CKEditor 5 - insert text
body: <p>Is it possible to insert text into the editor at current selection?</p>
  
  <p>I have tried</p>
  
  <pre><code>import Text from '@ckeditor/ckeditor5-engine/src/model/text';
  
  function insertText() {
    let text = new Text('test');
    ckEditor.model.insertContent(text, ckEditor.model.document.selection);
  }
  </code></pre>
  
  <p>where <code>ckEditor</code> is the editor object returned from <code>ClassicEditor.create</code></p>
  
  <p>code runs without error, but nothing happens</p>
  
  <p>I have managed to get similar code to work from within a plugin, but here I am trying to inject the text from the host app</p>
