How could I add my plugin attributes on this card ?

Traefik card

My Traefik plugin config :

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: cas-middleware
spec:
  casmiddleware:
    passportURL: "https://test.com:443"
    apiToken: token
    whitelist: 
      - /params
      - /test
    token:
      name: "AUTH"
      secretKey: "secret"
      duration: 10m

I tried to add these spec on my Traefik card, i see a lot of others plugin with there spec on the card like :

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: backend-retry
spec:
  retry:
    attempts: 20
    initialInterval: 300ms

This imported plugin have its attempts on its card.

I already tried a lot of stack overflow and internet solutions.
