How to make routes case insensitive

I've create API on CI4 and set all the routes then found out that all routes are case sensitive though I want to ignore case and match either way, how do I do it?

This should be routed with 
www.mydomain.com/api
www.mydomain.com/Api
$routes->group('api', function ($routes) {
    $routes->post('/', 'MyController::myFunction');
});

Never mind, I've implemented a function on $routes to ignore case;

$routes->setIgnoreCaseSensitive(true);

Be nice if you showed your code for the rest of the forum users.

What did you Try? What did you Get? What did you Expect?

@UzairAli001,

I trap case insensitive URLs in Controllers:

Code:

# ==========================================
public function urls($url='')
{
   // BaseController -> data['urls'];
   // $this->data['urls'] = case sensitive array of permitted URLs

   if( in_array($url, $this->data['urls']) ) :
      return view('v_subpage/'.$url .'/index', $this->data);

   elseif( empty($url) ) :   
      return view('v_homepage', $this->data);

   else:
      $this->data['title'] = $this->data['title'] . ' DOES NOT EXIST???';
      $this->data['menu']  = view('incs/_menu', $this->data);

      return view('v_subpage', $this->data);
   endif;   
}//
