Does Istio Egress support external HTTPS proxy to transparently proxy pod's traffic?

The problem is that the traffic from the pod does not go via configured proxy for specified sites.

There is a k8s app (node.js) that support HTTPS_PROXY environment variable, but does not support NO_PROXY. And there is a task to proxy traffic from the app to only specific sites.

I tried to deploy the Istio egres like this:

istioctl install --set profile=minimal \    --set values.pilot.env.PILOT_ENABLE_ALPHA_GATEWAY_API=true \    --set meshConfig.accessLogFile=/dev/stdout \    --set "components.egressGateways[0].name=istio-egressgateway" \    --set "components.egressGateways[0].enabled=true" \    --set meshConfig.outboundTrafficPolicy.mode=ALLOW_ANY

And applied two manifests:

---## ServiceEntry that describes external proxy#apiVersion: networking.istio.io/v1beta1kind: ServiceEntrymetadata:  name: external-proxyspec:  hosts:  - proxyext.external.site.local  ports:  - number: 3128    name: http    protocol: HTTP  location: MESH_EXTERNAL---apiVersion: networking.istio.io/v1beta1kind: VirtualServicemetadata:  name: route-to-proxyspec:  hosts:  - api.google.com  - api.usa.com  - someother.site.com  - en.wikipedia.org  http:  - match:    - port: 443    route:    - destination:        host: proxyext.external.site.local        port:          number: 3128

Then tried to send a request with curl to en.wikipedia.org from the container and it wasnt go via proxy, but go directly. The istio-proxy side container's log revealed this:

[2024-04-16T07:29:51.116Z] "- - -" 0 - - - "-" 813 110483 535 - "-" "-" "-" "-" "185.15.59.224:443" outbound|443||en.wikipedia.org 10.233.103.2:32854 185.15.59.224:443 10.233.103.2:32838 en.wikipedia.org -

What am i doing wrong here?
