Page activation workflow - Skip END step

Hi Team,
In Page activation workflow, we have two steps to complete the operation.

1 . Approve / Reject

2. End

whenever user approve the request, it is still asking to end the workflow to complete the request. We need to skip the END step, so I tried to remove but the workflow is running forever and the only option I get is to terminate the workflow manually in Instances.

we tried without deleting the end step, by creating custom Process step to terminate the workflow without manual intervention but no luck.
workflowSession.terminateWorkflow(workItem.getWorkflow()); 

Need your suggestions

Thanks!
