php - Does not show newly created module in Layout -

i'm trying list newly created module(account_test) copied "account" module in opencart 2.x (account module shows in backend system->design->layouts-> edit home layout). have duplicated account php & tpl files account_test & tpl files , change references account account_test in both admin & catalog module/language/view folders.

also, noticed in admin\controller\design\layout.php if statement add account & category modules layouts setting:

if ($this->config->has($code . '_status') || $module_data) {                 $data['extensions'][] = array(                     'name'   => $this->language->get('heading_title'),                     'code'   => $code,                     'module' => $module_data                 );              } 

if remove if condition :

        $data['extensions'][] = array(             'name'   => $this->language->get('heading_title'),             'code'   => $code,             'module' => $module_data         ); 

it add modules layouts view, none of them working except old modules

stuck in few days, ideas list newly created module layouts admin section , front end?

is module installed or not? if followed correctly must listed in admin->extension->modules. , there have first install , enable it. , make sure controller file named properly.

edit

$this->config->has($code . '_status') checks whether module installed or not i.e. in setting table or not. check in setting table module code.
