import * as Calendar from 'expo-calendar';
// this created the event fine
const eventId = await Calendar.createEventAsync(primaryCalendar.id, { ... });
// this retrieved the event fine
const event = await Calendar.getEventAsync(eventId);
// when this is called immediately after the previous steps, the Calendar app will say the event does not exist.
// if I wait for a few seconds before calling this, then it will work.
await Calendar.openEventInCalendarAsync({ id: eventId });
