I’m using Traefik as a Gateway API Controller.

I’m configuring an HTTPRoute and a TLSRoute.

With help of this excellent doc ([Advanced - Traefik](https://doc.traefik.io/traefik/expose/kubernetes/advanced/)) I managed to add Middlewares to my HTTPRoute using the `filter` property of type `ExtensionRef` of the RuleSpec of HTTP (from the Gateway API Spec: [Standard - Kubernetes Gateway API](https://gateway-api.sigs.k8s.io/reference/spec/#httprouterule)).

But TLSRoute doesn’t seem to have a similiar “TLSRouteRule filter” spec ([Standard - Kubernetes Gateway API](https://gateway-api.sigs.k8s.io/reference/spec/#tlsrouterule)).

So… how can I add a Middleware to a Traefik TCP Router created with TLSRoute from Gateway API (which doesn’t have the convenient filter field in its spec)?

Thank you in advance.
