Publish Facebook events that have been RSVP'd (Going) to O365 users' persoanl calendar. Currently, the Outlook mobile application for iOS is abe to connect to Facebook events but it does not pick up all RSVP events and does not show in O365 calendar online.
So basically the flow would be:
User accepts or submits to going to an event >
Microsoft Flow picks up the RSVP with full details (including other attendees if possible) >
Microsoft flow mirrors the event on the O365 users' calendar >
An email is sent to O365 users inbox confirming that a new event has been created for {reason}
