[k8sattributesprocessor] How to populate incoming metric values with k8s metadata correctly?

[sfc-gh-aivanou]

Hello!
I am a little bit confused by the k8sattributeprocessor documentation here: https://pkg.go.dev/github.com/open-telemetry/opentelemetry-collector-contrib/processor/k8sattributesprocessor#section-readme

I run otel collector as an agent, and have a prometheus scraper that scrapes metrics from the kube-state metrics.
Lets say that I get the following value:

kube_pod_container_resource_requests{namespace="my_namespace",pod="my_pod", node="my_node",resource="cpu",unit="core"} 0.1

Now I need to enrich this metric stream with several pod labels. What exactly should I provide as source for k8sattributesprocessor here to do so?
