OpenCart 3没有显示我的模块(OpenCart 3 not showing my module)

 我是OpenCart的新手，但我了解PHP和MVC平台。 我想让OpenCart的导入器从CSV导入一些产品，并为他们导入照片。  
 但是，在过去的两个小时里，我一直在努力试图在管理员中看到我的模块。 我创建了一个admin/controller/module/custom_importer.php ：  
<?php
class ControllerModuleCustomImporter extends Controller {

}
 
 和语言文件admin/language/en-gb/module/custom_importer.php ：  
$_['heading_title'] = 'Custom Importer';
 
 但是，在我的管理员中，我似乎根本找不到该模块。 这是最简单，最空的模块。 我究竟做错了什么？  
 Opencart：3.0.2.0版 

I'm fairly new to OpenCart but I know PHP and MVC platforms. I want to make an importer for OpenCart to import some products from a CSV and the photos for them. 
However, I've been struggling for the last 2 hours trying to see my module in the admin. I created an admin/controller/module/custom_importer.php: 
<?php
class ControllerModuleCustomImporter extends Controller {

}
 
and a language file admin/language/en-gb/module/custom_importer.php: 
$_['heading_title'] = 'Custom Importer';
 
However, in my admin I can't seem to find the module at all. It's the simplest, emptiest module. What am I doing wrong?

 这会有帮助吗？  
SELECT NVL (a.key, b.key) AS "KEY",
       NVL (a.text, b.text) as "TEXT",
       CASE
          WHEN a.key IS NOT NULL AND b.key IS NULL THEN
             'Insert'
          WHEN a.key IS NULL AND b.key IS NOT NULL THEN
             'Delete'
          WHEN a.key IS NOT NULL AND b.key IS NOT NULL AND a.text != b.text THEN
             'Update'
          WHEN a.key IS NOT NULL AND b.key IS NOT NULL AND a.text = b.text THEN
             'Nothing'
       END
          "CASE"
  FROM tablea a FULL OUTER JOIN tableb b ON a.key = b.key;

Would this help? 
SELECT NVL (a.key, b.key) AS "KEY",
       NVL (a.text, b.text) as "TEXT",
       CASE
          WHEN a.key IS NOT NULL AND b.key IS NULL THEN
             'Insert'
          WHEN a.key IS NULL AND b.key IS NOT NULL THEN
             'Delete'
          WHEN a.key IS NOT NULL AND b.key IS NOT NULL AND a.text != b.text THEN
             'Update'
          WHEN a.key IS NOT NULL AND b.key IS NOT NULL AND a.text = b.text THEN
             'Nothing'
       END
          "CASE"
  FROM tablea a FULL OUTER JOIN tableb b ON a.key = b.key;
