title: Gmail markup for online event
body: <p>While there is good documentation around sending markup emails for specifying offline event. <a href="https://developers.google.com/gmail/markup/reference/event-reservation" rel="nofollow noreferrer">Refrence</a> Can someone help me out on how to add handle an online event?
  The issue with offline event is that I need to enter a proper postal address, however in our case the location is simply a url.
  Things I have already tried</p>
  <ul>
  <li>Putting type of location as <code>VirtualLocation</code>, but that gives error</li>
  <li>Entering empty strings in <code>PostalAddress</code> fields</li>
  <li>Marking <code>eventAttendanceMode</code> as <code>https://schema.org/OnlineEventAttendanceMode</code>, it gives error</li>
  </ul>
  <p>Does gmail support markups for online events? Common sense says it should.</p>
