title: EventKit. How can I get videoconference url from EKEvent
body: <p>I have an event that has a meet or zoom link. However, I can't find a way to get the link of type <code>https://meet.google.com/...</code>. An example:</p>
  <pre><code>let calendars = eventStore.calendars(for: .event)
  var events: [EKEvent] = []
          
  for calendar in calendars {
       let oneMonthAfter = Date(timeIntervalSinceNow: 30*24*3600)
       let predicate =  eventStore.predicateForEvents(withStart: Date(), end: oneMonthAfter, calendars: [calendar])
              
       let collection = eventStore.events(matching: predicate)
       events.append(contentsOf: collection)
  }
          
  let event = events.first! // This event has a meet link associated but I can't get the link
  </code></pre>
  <p>EventKit has a class named <code>EKVirtualConferenceURLDescriptor</code> (more info <a href="https://developer.apple.com/documentation/eventkit/ekvirtualconferenceurldescriptor?changes=l_1&amp;language=objc" rel="nofollow noreferrer">here</a>). However, the documentation isn't good and only talks about creating a new one, not how we can get it from an existing event.</p>
