How to load Configuration Files as Array?

I am passing some environment settings to a view template but how do I pass it as an Array to avoid below error?

TypeError
Argument 2 passed to view() must be of the type array, object given

PHP Code:

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class TestConfig extends BaseConfig
{
    /*
    |--------------------------------------------------------------------------
    | CAPTCHA
    |--------------------------------------------------------------------------
    |
     */
    public $captcha = 1; 


PHP Code:

// Access config class with namespace
$config = config( 'Config\\TestConfig' );

echo view('login', $config); 


Try

PHP Code:

// Access config class with namespace
$config = config( 'Config\\TestConfig' );
$data['captcha'] = $config->captcha;
echo view('login', $data);
