What should be done so that htaccess does not block ajax request?

Question

JavaScript

Good afternoon ! I would like to ask if my htaccess is configured so that it is impossible to directly access .php files and therefore my ajax request is blocked, I would be very grateful if you could tell me how to either add the file to which I need to access to the exclusions or configure htaccess in another way here is what the console outputs

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule .* index.php?q=$0 [QSA]

<FilesMatch "\.(php)$">
Deny from all
</FilesMatch>

<FilesMatch "index.(php)$">
Allow from all
</FilesMatch>

AddDefaultCharset UTF-8
