Using envoy filter with redis proxy and service entry, how to solve "unknown" service in kiali?

I’m trying to set Istio mesh with AWS Elasicache.
Using the below manifests, it looks like working fine.

But the problem I got is from Kiali, it doesn’t recognize the service entry.

Anyone has idea to solve this ?
How the istio recognize it ?
