Using Policies with Spatie/Laravel-permissions

I want to add roles and permissions to a laravel forum app based on the tutorial here: Creating a Laravel Forum Using Laravel 8

However, this tutorial that demonstrates how to add roles and permissions manually without a package using a single guard, User Policy, Middleware and a LoginResponse class to handle redirection based on the role of the auth user.

I'm attempting to do something similar using the Spatie/Laravel-Permissions package. When doing this, I'm finding that the HasAnyRole method and the Can method are not recognized in certain areas of the code as shown below. Another reason I'm asking is that doing this with a Policy seems redundant.

Do I need policies (guards and gates?)? Is there a more efficient, cleaner way of adding roles and permissions using spatie/laravel-permissions?

User Model

use HasRoles; 

const DEFAULT = 1; 
const MODERATOR = 2;
const ADMIN = 3;

/** A type column was added to the User table migration **/
public function type(): int
{
    return (int) $this->type;
} 

public function isModerator(): bool
{
    return $this->type() === self::MODERATOR;
}

public function isAdmin(): bool
{
    return $this->type() === self::ADMIN;
}

UserPolicy class

const ADMIN = 'admin';

public function admin(User $user): bool
{
	return $user->isAdmin();
}

AuthServiceProvider Class

UserPolicy reference is added here

protected $policies = [
	User::class => UserPolicy::class;
];

CheckIfAdmin Middleware Class

Note: One issue I'm having here is that the "can" method is not recognized in the Auth

class CheckIfAdmin
{
		public function handle(Request $request, Closure $next, $guard = null) {

			//  In this condition, the hasAnyRole() method is not found in Auth::guard($guard)->user() 
			 if(Auth::guard($guard) && Auth::guard($guard)->user()->hasAnyRole(['super-admin', 'admin']) ){
					//
        	}

			// Also, in this condition, the can() method is not found in Auth::guard($guard)->user() 
			if(Auth::guard($guard)->user()->can(UserPolicy::ADMIN, User::class) {
 				return $next($request);
		   }
		   throw new HttpException(403, 'Forbidden');
		}
}

LoginResponse Class

No errors found in this code according to PHPStorm.

namespace App\Http\Responses;

use Laravel\Fortify\Contracts\LoginResponse as ContractsLoginResponse;

class LoginResponse implements ContractsLoginResponse
{
    public function toResponse($request)
    {
        if (auth()->user() && auth()->user()->hasRole('administrator')) {
            return redirect()->route('admin.index');
        }
        return redirect()->intended(config('fortify.home'));
    }
}
