Codeigniter4 Shared web hosting. Issue with configuring URLs

here is the thing. localhost development works fine. as I move to shared hosting try to configure codeigniter4 I'm facing issues with routes.

I use softaculouse to install CI4 on the main directory (public_html). when I try to configure the routes things work fine except when I write the domain name.

example

https://example.com/ (Issue) it will send me to https://example.com/public/ (Code 500) I contacted support they claim the issue in public folder I'm not allowed to add .htaccess so they deleted it for me .htaccess file in public. things work fine. however; when I write https://example.com/ works but the URL in the address bar changes to https://example.com/public

How to remove /public ? is it a .htaccess configuration?

is it an issue with Apache configuration from hosting company side?

by the way

https://example.com/home (No problem)

https://example.com/en (No Problem) after modifying routes using {locale}

htaccess in public_html

# To prevent access to .env and other files
<Files .*>
# Apache 2.2
<IfModule !mod_authz_core.c>
Order deny,allow
Deny from all
</IfModule>
# Apache 2.4
<IfModule mod_authz_core.c>
Require all denied
</IfModule>
</Files>

<IfModule mod_alias.c>
RedirectMatch 301 ^/$ https://example.com/public
</IfModule>

This is htaccess which initially was generated inside public folder (Its standard generated by composer i think)
