How to remove Kubernetes k8s.gcr.io/pause created by podman?

I've blindly followed some podman tutorial (German), which tricked me into creating a Kubernetics container.

I guess these commands caused that:

$ podman pod create --name somename
$ podman run --detach --pod=somename alpine:latest top

So I accidentally created that and even after podman system prune -a or so, the image k8s.gcr.io/pause and a container that calls itself an „infra container” and refuses to be removed remains.

Here some commands:

$ podman images                  
REPOSITORY                TAG     IMAGE ID      CREATED         SIZE

Note I do not use kubectl – nor do I have this installed. So this answer for Kubernetics did not help me.
