Laravel reverb - How to remove it?

I wanted to test Laravel Reverb, great tool, can't wait to use it in a new project, but at the moment I need to remove it from the current project because the client doesn't want the functionalities I was planning to use it for. I cannot remove it or I don't know how to do it and seems can't find informations online.

If I try to remove it with composer I get this error:

" Class "Pusher\Pusher" not found

at vendor\laravel\framework\src\Illuminate\Broadcasting\BroadcastManager.php:341"

Does anyone know how to remove it completely and safely?
