How to use the react-native-calendar-events.authorizationStatus function in react-native-calendar-events

async function addIOS(event: Event) {
  let status = await CalendarEventsIOS.authorizationStatus();

  if (status === 'undetermined') {
    try {
      // TODO(localization)
      await OkCancelAlert(
        'Add to Calendar',
        'To add this event to your calendar, you need to allow access to your calendar.'
      );
      status = await CalendarEventsIOS.authorizeEventStore();
    } catch (error) {
      console.log('Canceled: Add to Calendar');
      return false;
    }
  }

  if (status !== 'authorized') {

export async function addToCalendar(event: EventType): Promise {
	try {
		let authCode = await RNCalendarEvents.authorizationStatus()

		let authStatus =
			authCode === 'authorized' ? true : await requestCalendarAccess()

		if (!authStatus) {
			return false
		}

		return await saveEventToCalendar(event)
	} catch (error) {
		Sentry.captureException(error)
		console.error(error)
		return false
	}
}

    } else if (authStatus !== 'authorized') {
      await this.requestPermission();
    }
  }
