title: eventOpenTrigger runs every time change is happening to live event
body: <p>Goal is to add attendees synchronously into Calendar Event being created. I can add attendees just fine to Event, however, when as a user I am changing any conference data of Event manually (e.g. add attendee manually or put Location), it's going to run &quot;eventOpenTrigger&quot; again, even if a new event is not opening.</p>
  <p>Appscript.json below:</p>
  <pre><code>{
    &quot;timeZone&quot;: &quot;America/New_York&quot;,
    &quot;dependencies&quot;: {},
    &quot;exceptionLogging&quot;: &quot;STACKDRIVER&quot;,
    &quot;runtimeVersion&quot;: &quot;V8&quot;,
    &quot;oauthScopes&quot;: [
      &quot;https://www.googleapis.com/auth/calendar.addons.current.event.read&quot;,
      &quot;https://www.googleapis.com/auth/calendar.addons.current.event.write&quot;,
      &quot;https://www.googleapis.com/auth/calendar.addons.execute&quot;,
      &quot;https://www.googleapis.com/auth/script.external_request&quot;,
      &quot;https://www.google.com/calendar/feeds&quot;
    ],
    &quot;addOns&quot;: {
      &quot;common&quot;: {
        &quot;name&quot;: &quot;&quot;,
        &quot;logoUrl&quot;: &quot;&quot;,
        &quot;homepageTrigger&quot;: {
          &quot;runFunction&quot;: &quot;onHomePage_noevent&quot;,
        }
      },
      &quot;calendar&quot;: {
        &quot;currentEventAccess&quot;: &quot;READ_WRITE&quot;,
        &quot;name&quot;: &quot;&quot;,
        &quot;logoUrl&quot;: &quot;&quot;,
        &quot;homepageTrigger&quot;: {
          &quot;runFunction&quot;: &quot;onHomePage_noevent&quot;
        },
        &quot;eventOpenTrigger&quot;:{
          &quot;runFunction&quot;: &quot;onHomePage&quot; 
        }
      }
    }
  }
  </code></pre>
  <p>I don't want this to happen because I don't want my Add on to go to <code>onHomePage</code> while user manually changes any info of event.</p>
  <p>Workaround I have tried: I have also tried to completely remove <code>eventOpenTrigger</code>, and just try and check if there is a live event being created while the Add On is running, but I can't figure out how to do that either. I would prefer if <code>eventOpenTrigger</code> just function as normal and only got triggered when an event was opened, and not every time the opened event's details change.</p>
