How to set cookie existence condition on nginx for redirect?

Question

Nginx

I need the following conditions:
If the user requests the site address "/" and the sid cookie exists, then redirect to "/account/" If the user
requests any other page and the sid cookie does NOT exist, then redirect to "/"
left me:

location ~* ^/$ {
                if ($cookie_sid != "") {
                        rewrite ^(.*)$ /account/ last;
                }
        }

        location / {
                if ($cookie_sid = "") {
                        rewrite ^(.*)$ / break;
                }
                try_files $uri $uri/ /index.html;
                expires 7d;
        }

As a result, when the user goes to "/" and sid is there, he first goes to "/account/" and then immediately to "/".
And when there is no sid, then it's generally an error.
Or maybe try to transfer this processing to nodejs?
