Under the What Happens Next subheading I can see Select the pyspark kernel to unblock further steps of Kubeflow Notebooks and Kubeflow Spark Operator integration. But such kernel is not available from Notebooks (tried jupyter-scipy:v1.10.0 and jupyter-tensorflow-full:v1.10.0 images).

Are there any missing steps to run Kubeflow Notebooks and Kubeflow Spark Operator integration? If so, would be great to modify the doc accordingly.
