// The type we get from on retrieving the document from firestore:
type FromFirestore = {
  "meetingAgenda": string
  "startTime": firestore.Timestamp // 😱 This is a different type between the client and the admin sdks.
}

// The type we want in in our Frontend and Backend:
type Meeting = {
  meetingAgenda: string,
  startTime: Luxon.DateTime
}
