title: Where is the "Alternate email address" section in the Google Calendar options?
body: <p><a href="https://support.google.com/calendar/answer/37135?hl=en&amp;vid=0-441378315427-1485537150491&amp;visit_id=1-636211344784304823-3966805347&amp;rd=1" rel="nofollow noreferrer">This</a> official Google support page says you can respond to Google Calendar invites from alternative email addresses, if you add them via the "Alternate email address" section of the "edit notifications" calendar options window:
  <a href="https://i.stack.imgur.com/lircR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lircR.png" alt="Google calendar &quot;Edit Notifications&quot; page"></a></p>
  
  <p>But, while I can add the alternative email to Gmail, I don't see a "Alternate email address", in that window. I there an extra step I am missing? Or was that feature removed or moved, and the docs not updated (fairly typical Google move, unfortunately :( )</p>
