Reverse proxy nginx to application

Question

I have a synology and I want to link a subdomain to one of this application. This is the URL I usually use to access to this service:

192.168.0.17:5001//index.cgi?launchApp=SYNO.SDS.App.FileStation3.Instance&launchParam=openfile%3D%252FOliver%252F

But this is too long and I want to access it directly this mydomaine.com

How should I configure the server ?

I tried this but it doesn't work :

server {
    listen 80;
    listen [::]:80;

    resolver 89.2.0.1;

    server_name test.fr;

    location / {
        proxy_set_header        Host                $http_host;
        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_intercept_errors  on;
        proxy_http_version      1.1;

        proxy_pass http://192.168.0.17:5000/index.cgi?launchApp=SYNO.SDS.App.FileStation3.Instance&launchParam=openfile%3D%252FOliver%252F;

    }

}

Thanks a lot for your help!
