Am I changing the nginx location correctly?

Question

Nginx

location ~* ^/bitrix/admin/sale_(order|delivery|app_rest_sender).*\.php$ {
  add_header Content-Security-Policy "frame-ancestors https://адрес_вашего_Битрикс24;";
  proxy_pass $proxyserver;

With php-fpm as backend, will this location be like this?

location ~* ^/bitrix/admin/sale_(order|delivery|app_rest_sender).*\.php$ { 
                add_header Content-Security-Policy "frame-ancestors https://адрес_вашего_Битрикс24;";
                try_files       $uri @bitrix; 
                fastcgi_pass    $php_sock;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

Or not true?

It seems to be true, the only question is where the variable comes from php_sock. If from inside the nginx config, the dollar sign is not needed.
