orchestrating Sagemaker notebook instance with AWS step function

I am building a pipeline from ETL to complete ML lifecycle. I have used AWS glue notebooks for most of the ETL Job and I have created pipeline with step functions. Rest Machine learning work completed in sagemaker notebook instances with multiple notebooks. Now I want to use step functions to build end to end pipeline. Unfortunately I can't see any sagemaker notebook instance run function in step function as like aws glue job run. Am I missing something here. please help me to complete this gap.
