Event.ics returning RSVP from participants

[pierrebarroca]

Once created an Indico Event, I would like having the option of tracking every of every participant status via rsvp and have it synced seamlessly on my cern email/calendar

The current ics calendar that is sent to participants only includes:
ORGANIZER;CN=Indico:mailto:noreply-indico-team@cern.ch

There should be a way to add in this ICS myself as organizer and every attendee with a RSVP. Something like:
ORGANIZER;CN=Pierre Barroca;PARTSTAT=NEEDS-ACTION;CUTYPE=INDIVIDUAL:mailto:
pierre.barroca@cern.ch
ATTENDEE;RSVP=TRUE;CN=[name of attendee];PARTSTAT=NEEDS-ACTION;CUTYPE=INDIVIDUA
L;ROLE=REQ-PARTICIPANT:mailto:[email of attendee]

I somehow managed to make it work by editing the ics created/sent by indico as shown above and sending the ics file to a dummy email..
