How to use the iotex-antenna/lib/account/wallet.decrypt function in iotex-antenna

form.validateFields(async (err, values) => {
        if (err || !values || !values.password || !values.keystore) {
          this.setState({ isDecrypting: false });
          return;
        }
        const { password, keystore } = values;

        try {
          const keyObj = JSON.parse(keystore);
          const { privateKey } = decrypt(keyObj, password);
          const antenna = getAntenna(true);
          const account = await antenna.iotx.accounts.privateKeyToAccount(
            privateKey
          );
          this.props.dispatch(setAccount(account));
        } catch (e) {
          const msg = String(e);
