Block all IP's except HOME IP in Nginx Netdata virtual host file on Ubuntu Server 20.04

Question

I'm running Ubuntu Server 20.04, and have successfully set up netdata. My netdata's Nginx virtual host file looks like this:

upstream backend {
   server 127.0.0.1:19999;
   keepalive 64;
}

server {

auth_basic "Protected";
auth_basic_user_file /etc/nginx/netdata-passwords;

   server_name netdata.example.com;
   location / {
     proxy_set_header X-Forwarded-Host $host;
     proxy_set_header X-Forwarded-Server $host;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_pass http://backend;
     proxy_http_version 1.1;
     proxy_pass_request_headers on;
     proxy_set_header Connection "keep-alive";
     proxy_store off;
   }

    listen 443 ssl http2; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/netdata.example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/netdata.example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    add_header Strict-Transport-Security "max-age=63072000; includeSubDomains" always;

    ssl_trusted_certificate /etc/letsencrypt/live/netdata.example.com/chain.pem; # managed by Certbot
    ssl_stapling on; # managed by Certbot
    ssl_stapling_verify on; # managed by Certbot

}

server {
    if ($host = netdata.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

proxy_pass http://backend;
     proxy_http_version 1.1;
     proxy_pass_request_headers on;
     proxy_set_header Connection "keep-alive";
     proxy_store off;
   }
}

and my stub_status.conf virtual host file looks like this:

server {
     listen 127.0.0.1:80;
     server_name 127.0.0.1;
     location /nginx_status {
        stub_status on;
    allow 127.0.0.1;
    deny all;
     }
}

What do I need to do in my virtual host file to deny all IP addresses to netdata except my home address? Any examples would be much appreciated!
