Class 'App\Referer\RefParameter' not found

Laravel 7 gives the error Class 'App\Referer\RefParameter' not found

I am trying to capture

public function getReferer(Request $request): string
{
return $request->get('ref', '');
}

The error above is using up without even calling this package in a controller.

App\Referer\RefParameter is not a class provided by this package.

Is there a place where there is an implementation example with a little more detail. I have used Spatie packages in the past with a great ease but this one seems to be stumbling me.
