How can we handle Callback URL redirection in FD serverless app?

Hi Saif, Team,

Would like to add 1 more question in addition to the above 3:
Currently this servless app is being invoked onTicket creation event only. If we want this single serverless app to be invoked onTicketCreation, onTicketClose and onTicketUpdate events how would we need to modify our server.js so that it can be invoked on all 3 events. Could you please provide some samples for the same?
