Getting errors regarding "component" and "CRDs" when trying to install PushProxy with helm chart

Hi, I have tried to install pushproxy to my k8s cluster wiht helm chart but I received couple of errors:
Error: unable to build kubernetes objects from release manifest: [resource mapping not found for name: "pushprox-etcd-client" namespace: "prom-proxy" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1" ensure CRDs are installed first, resource mapping not found for name: "pushprox-etcd-proxy" namespace: "prom-proxy" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1" ensure CRDs are installed first, resource mapping not found for name: "prom-proxy-etcd" namespace: "prom-proxy" from "": no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1" ensure CRDs are installed first]

I was changing component in Values.yaml to kube-proxy, etcd and others but received below error.

Also I received CRDs errors.. Which CDRs I should install before isntalling helm chart?

Thanks!

Start with the Helm chart templates and Values.yaml, then compare the cluster's available APIs with the reported policy/v1beta1 PodSecurityPolicy and monitoring.coreos.com/v1 ServiceMonitor resources. Check which chart resources require those APIs and document the required compatibility or installation steps; done means the reported install errors are addressed.
