how do I run ci4 app inside a subfolder of wordpress

Lately, I have been trying to run a ci4 project inside a subfolder of the WordPress project, but so far no luck might be because I don't have a vast knowledge of htacess files.
htacess of WordPress projects 

Code:

# HTTPS forced by SG-Optimizer
<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END HTTPS
# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

and htacess of the ci4 project to hit the public folder

Code:

RewriteEngine on

RewriteCond $1 !^(index\.php|images|assets|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./public/index.php/$1 [L,QSA]

I would really appreciate any help I get from you guys.
Thanks in advance, happy coding
