How can I index files only from specific folder of my public/ - Nginx?

I have 2 txt files that I placed at /home/forge/laravel58/public/files; I want to index those 2 txt files when I goto my site/files

I've tried

location /files {
    #auth_basic "Restricted";
    #auth_basic_user_file /home/forge/laravel58/.htpasswd;
    alias /home/forge/laravel58/public/files;
    autoindex on;
}

Go to : site/files, and see

403 Forbidden Nginx
