Laravel Permissions only use roles

Hello, we have a simple app to create tickets and we're using the "spatie/laravel-permissions" package. Now we want to disallow certain functions using roles or show only certain functions if a certain role is given. But we want the Super Admin to always ignore/bypass this check.

We have put the following code in the AuthServiceProvider:

Gate::before(function ($user) {
    return $user->hasRole('admin') ? true : null;
});

But when i use this code in my Blade file, i still can't see the required function even when i have the role "admin".

@hasrole('processing')
    test
@endhasrole

I want the "admin" role to bypass all "@hasrole" checks.

What am i doing wrong?
