I can not connect the class through Composer. Maybe I'm doing something wrong?

Question

PHP

When connecting the class, it gives the following error:
Fatal error: Uncaught Error: Class 'application\controllers\FrontController' not found in D:\OpenServer\OSPanel\domains\forumedia\public\index.php on line 8

the connection comes from a file

<?php

use application\controllers\FrontController;

const INDEX_PAGE = 'title.php';

/* Инициализация и запуск FrontController */
$front = FrontController::getInstance();
$front->route();

/* Вывод данных */
echo $front->getBody();

1. in composer.json file:
"application\\": "application",
replace with "application\\": "application/",
2. Include in your autoload.php file:
require __DIR__.'/../vendor/autoload.php';
3. run composer commanddump-autoload
