Symfony My debug toolbar doesn’t appear on my website anymore

  debugging, symfony, toolbar

While debugging, I actually lost my debug toolbar (like, it doesn’t appear anymore on my website) so I tried various thing to have it back:

composer require symfony/profiler-pack
composer require symfony/apache-pack

And even:

composer remove apache-pack
composer require symfony/apache-pack

But I still can’t have it back. I found nothing that can help on the Internet.
Thanks !
