decisions service configuration in production

I have question on configuring the decisions service in aks, do we need to use LoadBalancer with sessionAffinity (which usually used for stateful service rather than restful service).

We are currently have service manifest configured and I guess we made it earlier to expose the service to public and get it assigned public IP so we can test it,

However in the official documentation the service is configured with type: ClusterIP

Would you please advice on what’s the correct way to configure decisions service in production,
