Can't query the metrics API

Question

I'm learning to use the metrics server it everything was going ok, I am using Docker for desktop and I installed the metrics server and the "top" command works fine but when I try to query the API using the following command

kubectl get --raw /apis/metrics.k8s.io/v1beta1/nodes/ | jq

I get

Error from server (NotFound): the server could not find the requested resource

I've been looking into this problem for a while, Tried altering the command but nothing worked I get the same Error

I thought the installation was the issue, But everything is configured right I think, When I run

 kubectl describe apiservice v1beta1.metrics.k8s.io

I Get
