If I understood well, they are not visible in the cluster's dashboard (default Kubernetes dashboard). How can I list them, and eventually modify them?
If you have Keda on the Kubernetes cluster, you can simply use kubectl to list the ScaledJobs and modify them.
To list the ScaledJobs:
kubectl get ScaledJob
Them to modify one of them:
kubectl edit ScaledJob {ScaledJobName}
