Google Calendar Event Sync Chrome Extension BugFix Assembly

We have previously launched an assembly to create this chrome extension. 

And now we would like to fix two bugs in this extension:

1. Events with attendees that have granted the event owner, edit or owner access to their calendar do not display.
   • Event created by James with Kristin and Mary as attendees
   • Kristin has granted James with owner access to her calendar
   • The event does not display in the extension
   • From what I can tell events may overwrite themselves when referenced by multiple calendars the user has access to.
2. Use of calendar sync tokens for incremental updates is causing 410 errors.
   • Need to find where and how to catch this error and resolve
   • So far the fix has been to clear the IndexDB manually in the Chrome Developer Console

Suggested update: (Nice to have)

• Code does not use Google's JS API library. Would prefer it did.
