below can handle this for you. Replace `RELEASE` and `NAMESPACE` with the name and namespace of the release: ```console KINDS=(service deployment) RELEASE=istio-ingressgateway NAMESPACE=istio-system for KIND in "${KINDS[@]}"; do kubectl --namespace $NAMESPACE --overwrite=true annotate $KIND $RELEASE meta.helm.sh/release-name=$RELEASE kubectl --namespace $NAMESPACE --overwrite=true annotate $KIND $RELEASE meta.helm.sh/release-namespace=$NAMESPACE kubectl --namespace $NAMESPACE --overwrite=true label...
