How to use the httpntlm/ntlm.createType3Message function in httpntlm

if (!challengeMatch) {
            return callback(this._formatError('Invalid login sequence while waiting for server challenge string', 'EAUTH', str, 'AUTH NTLM'));

        let type2Message = ntlm.parseType2Message(challengeString, callback);
        if (!type2Message) {
            return;
        }

        let type3Message = ntlm.createType3Message(type2Message, {
