Pod with some values was deployed, then I edited it kubectl edit pod <pod>, and now wanted to get back to the previous state (no longer have the values as someone else deployed it some time ago). Is it possible?

And second question. If someone deployed to GKE cluster with helm, is it possible (even though I have access to cluster and can see all kubectl get all) that I don't see those deployments with helm list but see the kubernetes pods ? - rephrasing it. Is it possible someone deployed to cluster with helm and I only see pods, no helm config with helm list ?

ps: helm and kubernetes works fine with other clusters or minikube:
