title: Allow guests to a VS Code Live Share session to run Python extension 'cells'
body: <p>When guests in a VS Code Live Share session try to run VS Code Python extension 'cells', they will get the following message in an error pop-up dialog in the lower right:</p>
  
  <pre class="lang-none prettyprint-override"><code>The host doesn’t allow running this command. 
  If needed, ask them to enable it.
  </code></pre>
  
  <p>Clicking on the "More info" button of the pop-up dialog, directs the guest to <a href="https://docs.microsoft.com/en-us/visualstudio/liveshare/reference/security" rel="noreferrer">https://docs.microsoft.com/en-us/visualstudio/liveshare/reference/security</a>.  I cannot find on this page where it describes how to allow guests to use certain features of particular VS Code extensions.</p>
  
  <p>As a host, how do I allow guests to my VS Code Live Share session to run VS Code Python extension 'cells'?</p>
