Laravel 2 different htaccess RewriteRule Problem - php

Question

In a project where we are using Laravel, we want a specific url to run another php file. But the url we want is constantly entering Laravel. We can't change project's DocumentRoot so we have 2 different .htaccess files.
When request come to api/v1/user/donate we want run /home/userName/project/subdomains/client/user.php. How can we do it?
Project Root: /home/userName/public_html
Project Root .htaccess file content;
<IfModule mod_rewrite.c>
# That was ONLY to protect you from 500 errors
# if your server did not have mod_rewrite enabled
RewriteEngine On
# RewriteBase /
# NOT needed unless you're using mod_alias to redirect
RewriteCond %{REQUEST_URI} !/public
RewriteRule ^(.*)$ public/$1 [L]
# Direct all requests to /public folder
</IfModule>
# php -- BEGIN cPanel-generated handler, do not edit
# Set the “ea-php80” package as the default “PHP” programming language.
<IfModule mime_module>
AddHandler application/x-httpd-ea-php80 .php .php8 .phtml
</IfModule>
# php -- END cPanel-generated handler, do not edit
Project's public folder .htaccess file content;
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Send Requests To Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
We used this rule for both .htaccess file but it didn't work;
RewriteRule ^api/v1/user/donate$ /subdomains/client/user.php [L,QSA]
