How to remove .html extension from address bar in nginx?

Question

Nginx

Hello. I want all links like example.com/page.html for my site example.com to be displayed in the address bar as example.com/page. In the same way, they should be available at example.com/page, because now it gives 404.
I read that you need to edit nginx.conf, but it doesn’t look like the ones shown in the guides for me. I don't have a location section.
Can you please tell me how to accomplish my task? I attach the content of nginx.conf

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
  worker_connections 768;
  # multi_accept on;
}

http {

  sendfile on;

  types_hash_max_size 2048;
  # server_tokens off;

   server_names_hash_bucket_size 64;
  # server_name_in_redirect off;

  include /etc/nginx/mime.types;
  default_type application/octet-stream;

  ssl_prefer_server_ciphers on;

  # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-enabled/*;
}


#mail {
#	# See sample authentication script at:

#	# auth_http localhost/auth.php;

# 
#	server {
#		listen     localhost:110;
#		protocol   pop3;
#		proxy      on;
#	}
# 
#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}

You have a folder next to nginx.conf called conf.d.
Here it connects, here you shove all your server settings, <project_name>.conf - you call it something like that, and in order to remove the extensions, write this to this file:
include /etc/nginx/conf.d/*.conf;

location / {
    rewrite     ^(/.*)\.html(\?.*)?$ $1$2 permanent;
    try_files   $uri/index.php $uri.php $uri/index.html $uri.html $uri/ $uri =404;
}
