Here's a workaround, you can call receiveMessageFromSQS method asynchronously.

   bulkReceiveFromSQS (queueUrl, totalMessages, asyncLimit, batchSize, visibilityTimeout, waitTime, callback) {
    batchSize = Math.min(batchSize, 10);

    let self = this,
        noOfIterations = Math.ceil(totalMessages / batchSize);

    async.timesLimit(noOfIterations, asyncLimit, function(n, next) {
        self.receiveMessageFromSQS(queueUrl, batchSize, visibilityTimeout, waitTime,
            function(err, result) {
                if (err) {
                    return next(err);
                }

                return next(null, _.get(result, 'Messages'));
            });
    }, function (err, listOfMessages) {
        if (err) {
            return callback(err);
        }
        listOfMessages = _.flatten(listOfMessages).filter(Boolean);

        return callback(null, listOfMessages);
    });
}

It will return you an array with a given number of messages
