'What is the role of ControllerManagerConfig generated in kubebuilder

I use kubebuilder to quickly develop k8s operator, and now I save the yaml deployed by kustomize to a file in the following way.

create: manifests kustomize ## Create chart
    cd config/manager && $(KUSTOMIZE) edit set image controller=${IMG}
    $(KUSTOMIZE) build config/default --output yamls

I found a configmap, but it is not referenced by other resources.

apiVersion: v1
data:
  controller_manager_config.yaml: |
    apiVersion: controller-runtime.sigs.k8s.io/v1alpha1
    kind: ControllerManagerConfig
    health:
      healthProbeBindAddress: :8081
    metrics:
      bindAddress: 127.0.0.1:8080
    webhook:
      port: 9443
    leaderElection:
      leaderElect: true
      resourceName: 31568e44.ys7.com
kind: ConfigMap
metadata:
  name: myoperator-manager-config
  namespace: myoperator-system

I am a little curious what it does? can i delete it?

I really appreciate any help with this.
