How to set up .htaccess in yii2 so that you can open the root folder from the browser?

Question

htaccess

There is such piece .htaccess. Tried adding "RewriteCond %{REQUEST_URI} !^/new/" , i.e. exclude /new/ from the redirect rule, but doesn't work.
As I understand it, it redirects everything to index.php. At the root of the site (next to .htaccess) is the new folder, which contains index.php. It is necessary that when you enter sitename.ru/new/, the new folder opens.

<IfModule mod_rewrite.c>
    # remove slash
    RewriteCond %{THE_REQUEST} \s/+(.+?)/+[?\s]
    RewriteRule /$ /%1 [R,L]

    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

    #Redirect HTTP to HTTPS
    RewriteCond %{HTTPS} off
    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    # если /admin, то в backend
    RewriteCond %{REQUEST_URI} ^/(admin)
    RewriteRule ^admin/assets/(.*)$ backend/web/assets/$1 [L]
    RewriteRule ^admin/css/(.*)$ backend/web/css/$1 [L]
    RewriteRule ^admin/js/(.*)$ backend/web/js/$1 [L]
    RewriteCond %{REQUEST_URI} !^/backend/web/(assets|js|css|js)/
    RewriteCond %{REQUEST_URI} ^/(admin)
    RewriteRule ^.*$ backend/web/index.php [L]

    RewriteCond %{REQUEST_URI} ^/(assets|css|js|images)
    RewriteRule ^assets/(.*)$ frontend/web/assets/$1 [L]
    RewriteRule ^css/(.*)$ frontend/web/css/$1 [L]
    RewriteRule ^js/(.*)$ frontend/web/js/$1 [L]
    RewriteRule ^images/(.*)$ frontend/web/images/$1 [L]
    RewriteRule ^(.*)$ frontend/web/$1 [L]
    
    RewriteCond %{REQUEST_URI} !^/(frontend|backend)/web/(assets|css|js)/
    RewriteCond %{REQUEST_URI} !index.php
    RewriteCond %{REQUEST_FILENAME} !-f [OR]
    RewriteCond %{REQUEST_FILENAME} !-d

    RewriteRule ^.*$ frontend/web/index.php
</IfModule>

Tried adding "RewriteCond %{REQUEST_URI} !^/new/"

Where did they add it? There are two rules that a request can match /new/.

# remove slash
    RewriteCond %{THE_REQUEST} \s/+(.+?)/+[?\s]
    RewriteRule /$ /%1 [R,L]

And more Here to these rules also it was necessary to add an exception. Or add this above the rest of the rules:
RewriteRule ^(.*)$ frontend/web/$1 [L]
RewriteRule ^new/ - [L]
