Why key value is not inserted in laravel config?

Question

Laravel

Why is the value true of the login key not inserted in the laravel config, from this:
config(['recaptcha.used.login', true]);
I allocated rights 775, tried 777, still does not insert,
recaptcha.php does not give errors:

<?php
return [
    'used' => [
        'order' => true,
        'login' => false,
    ],
    'public_key' => '',
    'private_key' => '',  
];

Answer 1

Configuration files are not meant to be changed at run time.

Answer 2

Those. Are you expecting this value to be written to the file itself? No, this won't happen.
