How to use the @zilliqa-js/util.bytes.hexToIntArray function in @zilliqa-js/util

kdfparams,
      mac: hashjs
        // @ts-ignore
        .hmac(hashjs.sha256, derivedKey, 'hex')
        .update(
          Buffer.concat([
            derivedKey.slice(16, 32),
            ciphertext,
            iv,
            Buffer.from(ALGO_IDENTIFIER),
          ]),
          'hex',
        )
        .digest('hex'),
    },
    id: uuid.v4({ random: bytes.hexToIntArray(randomBytes(16)) }),
    version: 3,
  });
};
