- Optional fields: `attendeePhoneNumber` (Whatsapp number), `notes` (What eats most of your time right now?)
- `name` and `email` go in `attendee` and `guests` is a list of emails; every other field goes in `bookingFieldsResponses` under its name.
- `location` is optional; without it the booking uses the event’s first location.
