Grpc web envoy filter config for latest istio version

[pranavnateri]

hi i am actually trying to apply the below mentioned envoy filter of grpc web for one of our microservices..

apiVersion: networking.istio.io/v1alpha3
kind: EnvoyFilter
metadata:
  name: bms-operator-platform-service
spec:
  workloadLabels:
    app: bms-operator-platform-service
  filters:
  - listenerMatch:
      listenerType: ANY
      listenerProtocol: HTTP
    insertPosition:
      index: FIRST
    filterType: HTTP
    filterName: "envoy.grpc_web"
    filterConfig: {}

however, i am getting the below error

error: error validating "/Users/pnateri/modules/kubernetes-deployment-dev/earth.xpressplay.net/cap-dev/subscription-service/envoy.yaml": error validating data: ValidationError(EnvoyFilter.spec): unknown field "filters" in io.istio.networking.v1alpha3.EnvoyFilter.spec; if you choose to ignore these errors, turn validation off with --validate=false

its probably because the above envoyfilter config belongs to an old istio version.. now i am currently on a latest istio version running on a EKS cluster(k8s version: 1.21).. but trying to apply the same envoyfilter config...

can you help me let me know what exactly could be the equivalent envoyfilter config of grpc web for a latest istio version?
