Add Kubernetes integration - kube-state-metrics:8080 or kube-state-metrics.kube-system.svc:8080

It's said in description

Generally kube-state-metrics runs a Deployment and is accessible via a service called kube-state-metrics on kube-system namespace, which will be the service to use in our configuration.

But when you push button Add Kubernetes integration u see settings
address - kube-state-metrics:8080

Is it expected that elastic stack should be deployed in kube-system namespace or what ?

and btw what is Bearer Token File /var/run/secrets/kubernetes.io/serviceaccount/token
will it be created during deploying agents or is it expected to exist in classical k8s ?
I do not have such file in my rke2 cluster

Im curious if you found the answer to this?
