impossible to show laravel debugbar with laravel 6

Question

I have installed laravel/debugbar in my laravel 6 project, however, I don't see it displayed on my page. I have tried several things :

• set APP_DEBUG=true in my .env file
• run php artisan config:clear, php artisan route:clear, php artisan cache:clear, php artisan config:clear & php artisan vendor:publish
• run composer dump-autoload
• set enabled => true in config/debugbar.php
• add the following in config/app.php

'Barryvdh\Debugbar\ServiceProvider',

'Debugbar' => 'Barryvdh\Debugbar\Facade',

Nothing helps, I still don't see the debugbar

Does somebody have an idea ? It would help an lot :)
