How should nginx/conf.d/*.сonf?

I am new to the whole NGINX server so please ignore my complete ignorance.

I need to insert the following in the server context of blocks would be in /etc/nginx/conf.d/wordpress.conf so I can serve my images as webp can someone please just let me know how it should be. Ugh I feel like such a newb and that it’s right in front of me and I am just completely missing it.

location ~* "wp-content\/(uploads\/)(.*.(?:png|jpe?g))" {
  add_header Vary Accept;
  set $image_path $2;
  if (-f "/sites/plastiwin.com/files/wp-content/smush-webp/disable_smush_webp") {
    break;
  }
  if ($http_accept !~* "webp") {
    break;
  }
  try_files /wp-content/smush-webp/$image_path.webp $uri =404;
}

But I think I’m doing something wrong т-т.
