## list_booking_event_types

List a connected provider's bookable event types so one can be chosen as the default.

Use before set_booking_default_event_type to obtain a valid `eventTypeRef` and the current connection id.

Do not call it on a provider the workspace has not connected; that is a not-found, not an empty list.
