How to use the @ledgerhq/errors.CurrencyNotSupported function in @ledgerhq/errors

export function checkAccountSupported(account: Account): ?Error {
  if (!getAllDerivationModes().includes(account.derivationMode)) {
    return new AccountNotSupported(
      "derivation not supported " + account.derivationMode,
      { reason: account.derivationMode }
    );
  }

  if (!isCurrencySupported(account.currency)) {
    return new CurrencyNotSupported("currency not supported", {
      currencyName: account.currency.name
    });
  }
}

const createTransaction = a => {
  throw new CurrencyNotSupported("tron currency not supported", {
    currencyName: a.currency.name
  });
};

const createTransaction = a => {
  throw new CurrencyNotSupported("neo currency not supported", {
    currencyName: a.currency.name
  });
};

const getTransactionStatus = a =>
  Promise.reject(
    new CurrencyNotSupported("tron currency not supported", {
      currencyName: a.currency.name
    })
  );

const getTransactionStatus = a =>
  Promise.reject(
    new CurrencyNotSupported("neo currency not supported", {
      currencyName: a.currency.name
    })
  );

const mainAccount = account.type === 'Account' ? account : parentAccount
  if (!mainAccount) throw new Error('an account expected')
  const supportedError = checkAccountSupported(mainAccount)
  if (supportedError) {
    throw supportedError
  }
  const { type } = decodeAccountId(mainAccount.id)
  if (type === 'mock') return mockAccountBridge
