title: How to make text-align: center in google app-script (Calendar)?
body: <p>I new one in app-script, and I want just paste and align text using CardService.newTextParagraph()</p>
  <pre><code>CardService.newTextParagraph()
          .setText(text)
  </code></pre>
  <p>I want use something like this</p>
  <pre><code>CardService.newTextParagraph()
          .setText(text)
          .setAlignment(DocumentApp.HorizontalAlignment.CENTER);
  </code></pre>
  <p>But its function and enum available only in the Document app.</p>
  <p>By default in addon text aligned to the left. I just want to align it in the center.
  Have anybody some advice or suggestion, how I can do it?
