Cannot use HTTP Cache plugin

I am using Traefik v2.4.x via Helm chart as Kubernetes Ingress Controller.
Created a middleware as follows:

        limit: 200Mi
        maxTTL: 900

But Traefik controller fails with next error:

plugin: unknown plugin type: httpCache

Experimental plugin is enabled en Helm chart btw, and this creates a /plugins-storage directory but completely empty.

Anyone facing this similar issue? I am not familiarised yet with Traefik ecosystem so do not understand properly plugins system yet.

So apparently HTTP Cache - Traefik Enterprise Documentation is a Enterprise only feature not present in Proxy: Overview - Traefik
