Istio/Virtual service - Rewrite rule for URI with path parameter - kubernetes

Question

What is the correct syntax for rewriting URI with a path parameter? I'd like to rewrite all requests matching
/my-service/requests/{requestId}/history (regardless of value of requestId path parameter) to
/requests/{requestId}/history.
Please note there is already another rule for /my-service/requests/send.
Thanks
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: my-service
namespace: world
spec:
hosts:
- "*"
gateways:
- internal-gateway.istio-system
http:
- match:
- uri:
prefix: "/my-service/requests/send"
ignoreUriCase: true
rewrite:
uri: "/requests/send"
route:
- destination:
host: my-service.world.svc.cluster.local
port:
number: 8080
- match:
- uri:
regex: "/my-service/requests/.*/history". //<=for all path parameters
ignoreUriCase: true
rewrite:
uri: "/my-service/requests/{requestId}/history" //<=??????
route:
- destination:
host: my-service.world.svc.cluster.local

Matches to URIs are evaluated in order, thus it can be configured like this:
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: my-service
namespace: world
spec:
hosts:
- "*"
gateways:
- internal-gateway.istio-system
http:
- match:
- uri:
prefix: "/my-service/requests/send"
ignoreUriCase: true
rewrite:
uri: "/requests/send"
route:
- destination:
host: my-service.world.svc.cluster.local
port:
number: 8080
- match:
- uri:
prefix: "/my-service/requests"
ignoreUriCase: true
rewrite:
uri: "/requests"
route:
- destination:
host: my-service.world.svc.cluster.local
port:
number: 8080
