Why is NGINX forced to unzip GZ?

Question

Nginx

The essence of the problem:
An archive with a sitemap
in the form of a sitemap-1,xml.gz file lies on the GZ server and when you try to open https://site.com/sitemap-1,xml.gz
in a browser - an error 404 , but when you try open https://site.com/sitemap-1,xml - opens unzipped file... what to do with it? nginx config responsible for this part:

location ~ ^/sitemap([0-9\-]*)\.xml(|\.gz) {
      	root /home/mygeoservices.prod/public_html/sitemaps/$host/;
        }
