Jupyterlab with Jupyter enterprise gateway in K8s environment

Hi, I am trying to deploy Jupyterlab along with Jupyter enterprise gateway in a K8s cluster to start and culling the idle pyspark kernels in a user specific K8s namespace. Both Spark and Jupyterlab+JEG are running on same K8s cluster. I am deploying standalone Jupyterlab without JupyterHUB. I am not able to find any reference to follow for this use case. Please let me know if anyone has done similar type of setup.
Thanks in advance for your help!
