How to enable mTLS between Kong Pod and any workload (having a sidecar) in PERMISSIVE mode?

I am enforcing PERMISSIVE mTLS mode using PeerAuthentication in my namespace. My kong deployment along with my target workload both have sidecars enabled (in the same namespace). However, when I check kiali, the traffic between the kong pod and the workload is not encrypted. However, between any other pods having sidecars have their traffic encrypted. Shouldn’t the traffic between kong pod and workload be encrypted as both have sidecars?
