Migrate from NGINX to Istio

1

Help me to translit Ingress to VirtualService.
I have this ingress and it works:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-https-service
  namespace: cnv-dev
  annotations:
    meta.helm.sh/release-name:  example-https-service
    meta.helm.sh/release-namespace: cnv-dev
    nginx.ingress.kubernetes.io/app-root: /
    nginx.ingress.kubernetes.io/backend-protocol: HTTPS
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/use-regex: 'true'
spec:
  tls:
    - hosts:
        - dev-cnv-srv.example.com
      secretName: cnv-tls-certs
  rules:
    - host: dev-cnv-srv.example.com
      http:
        paths:
          - path: / example-https-service(/|$)(.*)
            pathType: Prefix
            backend:
              service:
                name:  example-https-service
                port:
                  number: 8090

How should I translate it to VirtualService properly?
