  <p>My workaround is to use the <strong>Gmail API</strong> to read the users' emails and extract the Flight Confirmation Number with a regular expression.</p>
  
  <p>This is not preferable as it is prone to error and requires permission from the user to read their emails.
  I'd rather let Google extract this information since they are already doing it.</p>
  
  <p><strong>Is it possible access this information from an automatically created event?
  If not, why is Google restricting this information?</strong></p>
