Forward real client ip through kong to my pod

Hi, I need your help here
I’m using kong with istio sidecar installed at AWS with a Network loadbalancer
What i’m trying to do: get client real ip header in my pod…

I’m following this: Istio / Proxy protocol on AWS NLB and Istio ingress gateway
and this is the envoy filter applied

apiVersion: networking.istio.io/v1alpha3
kind: EnvoyFilter
metadata:
  name: proxy-protocol
  namespace: kong-system
spec:
  workloadSelector:
    labels:
      app.kubernetes.io/instance: kong
  configPatches:
  - applyTo: LISTENER
    patch:
      operation: MERGE
      value:
        listener_filters:
        - name: envoy.filters.listener.proxy_protocol
        - name: envoy.filters.listener.tls_inspector
