Unable to Install kubernetes-nmstate-operator on OKD4.15 Bare Metal Cluster – constraints not satisfiable Error

[ALL-SPACE-Anas]

I'm attempting to install the kubernetes-nmstate-operator in my OKD 4.15 bare metal cluster, but I'm encountering issues with the operator not resolving correctly through Operator Lifecycle Manager (OLM). I'm following the documentation here: https://docs.okd.io/4.15/networking/k8s_nmstate/k8s-nmstate-about-the-k8s-nmstate-operator.html#installing-the-kubernetes-nmstate-operator-CLI_k8s-nmstate-operator

It doesn't help that the operator isn't available when trying to install from webUI.

I couldn't create a subscription on redhat-operator source (understandably) so created a subscription with community-operators:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: kubernetes-nmstate-operator
  namespace: openshift-nmstate
spec:
  channel: stable
  installPlanApproval: Automatic
  name: kubernetes-nmstate-operator
  source: community-operators
  sourceNamespace: openshift-marketplace

The community-operators CatalogSource is healthy according to the Subscription status. However, the operator never installs. The Subscription status shows the following error:

message: 'constraints not satisfiable: no operators found in package kubernetes-nmstate-operator
in the catalog referenced by subscription kubernetes-nmstate-operator, subscription exists'
reason: ConstraintsNotSatisfiable
type: ResolutionFailed

So, some questions,

• I'm trying to install it as a requisite for OKD virtualization. Does OKD support installing the kubernetes-nmstate-operator from community-operators, or is this operator only available via Red Hat’s certified catalog?
• If community-operators doesn't include it, what is the recommended way to deploy this operator on OKD? Should I use https://github.com/nmstate/kubernetes-nmstate? Anything in particular I need to keep in mind when deploying it from kubernetes-nmsate repo?
• Is there an upstream Helm chart or manifest bundle I should use?
• Are there any OKD-specific limitations or recommendations around using this operator in bare metal environments?

Deployed nmstate from https://github.com/nmstate/kubernetes-nmstate and so far it appears to work as expected.
