How to use the pyqs.utils.get_aws_region_name function in pyqs

def get_or_create_queue(queue_name):
    region_name = get_aws_region_name()
    sqs = boto3.resource('sqs', region_name=region_name)
    try:
        return sqs.get_queue_by_name(QueueName=queue_name)
    except ClientError as exc:
        non_existent_code = 'AWS.SimpleQueueService.NonExistentQueue'
        if exc.response['Error']['Code'] == non_existent_code:
            return sqs.create_queue(QueueName=queue_name)
        else:
            raise

def get_conn(region=None, access_key_id=None, secret_access_key=None):
    if not region:
        region = get_aws_region_name()

    return boto3.client(
        "sqs",
        aws_access_key_id=access_key_id,
        aws_secret_access_key=secret_access_key, region_name=region,
    )
