Redirect traefik dashboard from www -> non-www and http -> https

Traefik Traefik v3 (latest)

Hi, here is the situation:
I'm able to redirect traffic from http to https on the Traefik dashboard.
I'm also able to redirect www -> non-www AND http -> https on a wordpress container.
The only part missing is redirecting www -> non-www on the traefik dashboard. Here is my config:

TRAEFIK:
    command:
      - "--log.level=${TRAEFIK_LOG_LEVEL}"
      - "--accesslog=true"
      - "--api.dashboard=true"
      - "--api.insecure=true"
      - --log.filepath=/var/log/traefik.log
      - --accesslog=true
      - --accesslog.filepath=/var/log/traefik-access.log

      - "--ping.entrypoint=ping"
      - "--entryPoints.ping.address=:8082"
      - "--entryPoints.http.address=:80"
      - --entrypoints.http.http.redirections.entrypoint.to=https
      - --entryPoints.http.http.redirections.entrypoint.scheme=https
      - "--entryPoints.https.address=:443"
      - "--providers.docker=true"
      - "--providers.docker.endpoint=unix:///var/run/docker.sock"
      - "--providers.docker.exposedByDefault=false"
      - "--certificatesresolvers.letsencrypt.acme.tlschallenge=true"
      - "--certificatesresolvers.letsencrypt.acme.email=${TRAEFIK_ACME_EMAIL}"
      - "--certificatesresolvers.letsencrypt.acme.storage=/etc/traefik/acme/acme.json"
      - "--metrics.prometheus=true"
      - "--metrics.prometheus.buckets=0.1,0.3,1.2,5.0"
      - "--global.checkNewVersion=true"
      - "--global.sendAnonymousUsage=false"
    labels:
      - "traefik.enable=true"

      #following 4 lines do not work

      - traefik.http.middlewares.redirect-to-non-www-dashboard.redirectregex.permanent=true

      - "traefik.docker.network=traefik-network"

I'm using traefik:v3.3. Any idea ?
