How do you include a global class in laravel

I would like to include a class for every controller to use. Here is what I tried with no luck.

In the Controller.php file, I added this line of code:

use App\Lib\RequestType;

Then in my controller UserController.php, I called a test function.

dd(RequestType::test());

But a fatal error is thrown.

Class 'App\Http\Controllers\RequestType' not found

What is laravel looking for the class in the Controllers folder. Shouldn't UserController inherit the Controller class?

Thanks in advance
