Functionally not clear of the Dashboard ingressRoute in the Helm Chart `traefik-8.0.x`

It is not clear to me how the dashboard-hook-ingressroute.yaml in the Helm Chart is working.

  1. What is the entryPoints: - traefik? There is an entry entryPoints.traefik.address=:9000' in the pod config but nothing beyond that.
  2. The ingressRoute tries to match api@internal but there is no Service of kind TraefikService deployed. There is nothing like that in the Helm chart.

How could I use the Helm Chart traefik-8.0.0 to have a dashboard that is accessible from outside and also be able to add Middleware?
