Proxy response cookie

Good day!
The essence of the problem is to make it so that what when two different calls, but with the same cookie, get to the same node

I have nginx config it works well

upstream events {
    hash $cookie_WSToken consistent;
    # clients-events-node2
      server 192.168.4.171:5212;
    # clients-events-node1
      server 192.168.4.171:5211;
}
    location / {
        access_log /var/log/nginx/events.log detailed2;
        proxy_redirect http:// https://;
        proxy_set_header Host $http_host;
        proxy_hide_header X-Powered-By;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Port $server_port;
        proxy_pass http://events;
        proxy_read_timeout 2700;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_hide_header       Set-Cookie;
        proxy_ignore_headers    Set-Cookie;
        proxy_set_header        Cookie "";

how can I transfer this configuration to traefik?
specifically interested in how to do it: hash $cookie_WSToken consistent;
I tried like this:

      - "traefik.enable=true"
      - "traefik.docker.network=${APP_UID}-traefik-network"
      - "traefik.http.routers.${APP_UID}-traefik.entrypoints=httponly"
      - "traefik.http.routers.${APP_UID}-traefik.rule=Host${TRAEFIK_VIRT_HOST}"
      - "traefik.http.routers.${APP_UID}-traefik-secure.entrypoints=${APP_UID}-https"
      - "traefik.http.routers.${APP_UID}-traefik-secure.rule=Host${TRAEFIK_VIRT_HOST}"
      - "traefik.http.routers.${APP_UID}-traefik-secure.tls=true"
      - "traefik.http.routers.${APP_UID}-traefik-secure.service=${APP_UID}-traefik"
      - "traefik.http.services.${APP_UID}-traefik"
      - "traefik.http.services.${APP_UID}-traefik.loadbalancer.server.port=${APP_PORT}"
      - "traefik.http.services.${APP_UID}-traefik.loadbalancer.sticky.cookie=true"
      - "traefik.http.services.${APP_UID}-traefik.loadbalancer.sticky.cookie.secure=true"
      - "traefik.http.services.${APP_UID}-traefik.loadbalancer.sticky.cookie.httpOnly=true"
      - "traefik.http.services.${APP_UID}-traefik.loadbalancer.sticky.cookie.name=WSToken"

in the access log I see that this cookie is being replaced

  "downstream_Set-Cookie": "WSToken=http://172.33.16.3:5000; Path=/; HttpOnly; Secure",
  "origin_Set-Cookie": "WSToken=http://172.33.16.3:5000; Path=/; HttpOnly; Secure",
  "request_Cookie": "WSToken=DEyMDEtODI0My00YTVhLWEyN2UtMTk4Y2U4ZTMwMTg5",
