URL paths to query params in NGINX

Question

I want to convert an Apache 2.4 configuration to NGINX. I found that NGINX does not pay attention to the htaccess...

I have an Application that uses this URL structure https://app.com.ar/admin/configuracion/lalala

where configure and lala are actually variables that look like path, but are used as query params in PHP.

The original configuration in Apache is this

RewriteEngine On

RewriteCond %{SCRIPT_FILENAME} !-d  
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^([A-Za-z0-9-]+)/?$ index.php?page=$1  [L]
RewriteRule ^([A-Za-z0-9-]+)/([A-Za-z0-9-]+)?$ index.php?page=$1&section=$2 [L]
RewriteRule ^([A-Za-z0-9-]+)/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)?$ index.php?page=$1&section=$2&id=$3 [L]

I found a site that converted it to an NGINX rule but it didn't work, it left me this

location / {
  if ($script_filename !~ "-d"){
    rewrite ^/([A-Za-z0-9-]+)/?$ /index.php?page=$1 break;
  }
  rewrite ^/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)?$ /index.php?page=$1&section=$2 break;
  rewrite ^/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)?$ /index.php?page=$1&section=$2&id=$3 break;
}

In conclusion, I need to have urls like this: https://app.com.ar/admin/configuracion/lalala

and in NGINX to be able to decompose it so that it can know how to direct it to the app with a format like this /index.php?page=$1&section=$2&id=$3 so far no luck. I wanted to ask if anyone has the experience and what solution I can give you!
