How can I pass 2 parameters to my middle-ware on my admin controller

I have an admin-controller and i want to passe to it middle-ware to parameters to allow Super Admin to do admin stuff.

Here my controller:

class adminController extends Controller
{
    public function __construct(){

        $this->middleware('admin');
    }
    public function showGenerateCode(){
        $code ="";
        return view('create_code',compact('code'));
    }
    public function generateCode(Request $request){
        $phone = $request['phone'];
        $code = "";
        $user = User::where('phone' ,'=',$phone)->first();
        if($user){
            $code = "Ce numero de telephone et deja associé a un utilisateur";
            return view('create_code',compact('code'));
            //dd($code);
        }
        else{
            $code = "Code d'autorisation générer avec succé : ".substr($phone,1,3).rand(1000000,9999999);
            return view('create_code',compact('code'));
        }
    }
}
