How to use the expo-contacts.getContactsAsync function in expo-contacts

export async function removeAllChildrenFromGroupWithNameAsync(groupName: string) {
  try {
    const groupId = await ensureGroupAsync(groupName);

    const { data: contacts } = await Contacts.getContactsAsync({ groupId });

    );
  } catch ({ message }) {
    // tslint:disable-next-line no-console
    console.error(message);
  }
}

export async function fetchContacts(
  kit: ContractKit

  const contacts = await getContactsAsync({
    fields: [Fields.PhoneNumbers, Fields.Image],

  const rawContacts = fromPairs(filteredContacts.map((contact) => [contact.id, contact]))

  // @ts-ignore
  const phoneNumbersToContacts = createPhoneNumberToContactMapping(filteredContacts)

  const phoneNumbersByAddress = await lookupPhoneNumbersOnAttestations(kit, phoneNumbersToContacts)

  const contact = contacts[0];
  Contacts.addExistingContactToGroupAsync(contact.id, groupId!);
}
