How to enable metrics in Lens

I want to enable metrics for my k8s cluster.
I know I need to install the helm chart from bitnami/kube-prometheus
I’m wondering what kind of docker images are needed for metrics to work in Lens.

Please check the documentation regarding enabling metrics in Lens Enabling cluster metrics - Lens Documentation

If you have already installed Prometheus with Helm and do not want to let Lens install them. Please check Metrics section in Cluster Settings. There you can see if Lens has automatically detected your prometheus installation. If not, you can provide the service yourself. Hope this helps!
