Convert .htaccess rules to nginx format

Question

I bought a ready-made Laravel script that was developed to run on Apache server, and the developer doesn't support to Nginx rewrite rules. Can someone help me? When I try to access the system on my Nginx server it gives multiple redirects error. I've tried it in several ways and I can't, I even used online converters, but it doesn't work.

This is the original .htaccess from the script:

DirectoryIndex index.php
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes
    </IfModule>

    RewriteEngine On
    <IfModule mod_ssl.c>
        RewriteCond %{HTTPS} off
        RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
    </IfModule>

    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    RewriteCond %{THE_REQUEST} /index\.php/(.+)\sHTTP [NC]
    RewriteRule ^ /%1 [NE,L,R]
    
    RewriteCond %{SCRIPT_FILENAME} !-d
    RewriteCond %{SCRIPT_FILENAME} !-f
    RewriteRule ^ index.php [L]
    
    RewriteCond %{REQUEST_URI} !^/public/
    RewriteRule ^ index.php [L]
    
</IfModule>
