minikube - Container image "k8s.gcr.io/kube-proxy:v1.22.3" already present on machine

Question

I deleted the minikube cluster by minikube delete and then remove the .minikube folder. When I start minikube cluster I can see event message like:

22m         Normal    Scheduled           pod/kube-proxy-b2lqg                            Successfully assigned kube-system/kube-proxy-b2lqg to minikube-m02
22m         Normal    Pulled              pod/kube-proxy-b2lqg                            Container image "k8s.gcr.io/kube-proxy:v1.22.3" already present on machine
22m         Normal    Created             pod/kube-proxy-b2lqg                            Created container kube-proxy
22m         Normal    Started             pod/kube-proxy-b2lqg                            Started container kube-proxy
22m         Normal    SuccessfulCreate    daemonset/kube-proxy                            Created pod: kube-proxy-48qfw
22m         Normal    SuccessfulCreate    daemonset/kube-proxy                            Created pod: kube-proxy-b2lqg

My question is where is the container image kept? I already deleted the .minikube folder. I checked on my host machine and there is no such image.
