Trigger and/or monitor Automated Data Labeling Job

I am following the documentation https://docs.aws.amazon.com/sagemaker/latest/dg/sms-automated-labeling.html#sms-auto-labeling-ec2 and I have created a Ground Truth labeling job for object detection. I also enabled automated data labeling when creating the job. I have roughly 5000 images in my dataset. I have manually labelled ( by creating myself as a worker ) 129 of these images. How many do I need to label before the automated labeling job triggers? How do I know if a job was triggered/succeeded/failed etc?

Thanks
