User Community Feedback

When using the XML API, the attendees receives the invitation email but the invite.ics is missing. However, if I manually add an attendee using the Webex App, the invite.ics is present.

I contacted the support and says it is because of functionality difference. Can we enable this to XML API too? We've been using the XML API since and needed the RSVP functionality to work when sending invites. We are considering to migrate to the REST API but our account seems to be non CI enabled.
