Helper file not registering

Hello, I am trying to set up a bitwise authentication. For this I am trying to create a Helper file (app/Helpers/RoleHelper.php). So that I can check the bits to the defined roles. Sadly enough the file / namespace is not found.

RoleHelper.php

namespace App\Helpers;

class RoleHelper
{
    const NONE = 0b0000;
    const USER = 0b0001;
    const EMPLOYEE = 0b0010;
    const ADMIN = 0b0100;

    const EMPLOYEE_USER = self::USER | self::EMPLOYEE; // 0011
    const ADMIN_ALL = self::USER | self::EMPLOYEE | self::ADMIN; // 0111
}

Composer.json

"autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/",
            "App\\": "app/"
			// Tried this to in the past "App\\Helpers\\": "app/Helpers/"																						
        },
        "files": [
            "app/Helpers/RoleHelper.php"
        ]
    },

I did the "composer dump-autoload"

I tried use App\Helpers\RoleHelper; I tried adding the \App\Helpers\RoleHelper::EMPLOYEE directly.

I realy am at a loss here
