Codeigniter 4 Load settings from database

I would like to load few settings that is previously stored in Database (e.g. site language, site name etc.) and those settings will be used everywhere in the application. Previously in Codeigniter 3 I've done this by adding below code in application/config/config.php file.

Code:

require_once(BASEPATH . 'database/DB.php');
$db =& DB();
$config['general_settings'] = $db->get('general_settings')->row();
$config['languages'] = $db->get('languages')->result();
$db->close();

But I'm bit confused about to Codeigniter 4 where or in which file I should put this code to get expected result. Any suggestion?
