Testing:

@Jonsy13 and I had tested it In both cluster-scope Installation and namespace -scope Installation, Control plane and Execution plane components are working as expected, predefined workflow(podato-head) and pod-delete experiment are also working* fine.
Note: Need to do the testing for other experiments also.
