how to ingress-nginx forward&rewrite external url

Question

I want something, I am using k8s. When I click www.example.com/webtv, I want to redirect cloudfront URL(cloudfront.com/webtv) but, I want it to go to www.example.com/webtv not cloudfront.com/webtv

nginx.ingress.kubernetes.io/stream-snippet: |
  server {
    listen 80;
    server_name www.asd.com;
    
    set $upstream_webtv asd123asd.cloudfront.net/webtv;

    location / {
      rewrite ^/webtv(.*)$ /$1 break;

      gzip on;
      add_header Last-Modified '$upstream_http_date';
      expires 30d;
      add_header Cache-Control "public";

      proxy_set_header Host $upstream_webtv;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_pass https://$upstream_webtv/$1;
    }
  }
