title: openByUrl() does nothing
body: <p>Brand new at this. </p>
  
  <p>I thought the following code in Google Apps Script would simply open a sheet in another window. But nothing happened. Nothing. </p>
  
  <p>Here's my code:</p>
  
  <pre><code>function OpenaSheet() {
    SpreadsheetApp.openByUrl('https://docs---------Blanked out on purpose-------------')
  
  }
  </code></pre>
