Event Listener Not Working

I'm using Laravel 11, and have the following Listener created to monitor for Lockout Events. The Lockout event is NOT logged, nor is the notification is not sent to the Super Admin. Any suggestions as to why this isn't working? I have this similar functionality that is working in a Laravel 10 application. The only difference is the Laravel 10 application is using Breeze, and the Laravel 11 application is using Jetstream.

Here is my Listener

<?php

namespace App\Listeners;

use App\Models\User;
use App\Notifications\LockedOutUser;
use Illuminate\Auth\Events\Lockout;
use Illuminate\Support\Facades\Log;

class UserLockedOutNotification
{
    /**
     * Handle the event.
     */
    public function handle(Lockout $event): void
    {
        // Log the lockout event
        Log::info('User locked out due to too many login attempts.', ['request' => $event->request->input('email')]);
        $user = User::role('Super Admin')->first();
        $user->notify(new LockedOutUser($event->request->input('email')));
    }
}

And this is the Notification, I'm hoping to use the Slack Channel, but for troubleshooting purposes I'm using the Mail option and this is working with all other notifications.

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;
use Illuminate\Notifications\Slack\SlackMessage;

class LockedOutUser extends Notification
{
    use Queueable;

    public string $email;

    /**
     * Create a new notification instance.
     */
    public function __construct($email)
    {
        //
        $this->email = $email;
    }

    /**
     * Get the notification's delivery channels.
     *
     * @return array<int, string>
     */
    public function via(object $notifiable): array
    {
        return ['mail'];
    }

    /**
     * Get the Slack representation of the notification.
     */
    public function toSlack(object $notifiable): SlackMessage
    {
        return (new SlackMessage)
            ->text('A User has been locked out.')
            ->text('Email: '.$this->email)
            ->text('URL: ' . url('/'));
    }

    /**
     * Get the mail representation of the notification.
     */
    public function toMail(object $notifiable): MailMessage
    {
        return (new MailMessage)
            ->line('A User has been locked out.')
            ->line('Email: '.$this->email)
            ->line('URL: ' . url('/'));
    }

    /**
     * Get the array representation of the notification.
     *
     * @return array<string, mixed>
     */
    public function toArray(object $notifiable): array
    {
        return [
            //
        ];
    }
}

Any help or suggestions would be greatly appreciated!

UPDATE: If I use the FortifyServiceProvider to log the event and send the notification it works, but it doesn't log through my Listener.

RateLimiter::for('login', function (Request $request) {
            $throttleKey = Str::transliterate(Str::lower($request->input(Fortify::username())).'|'.$request->ip());
            return Limit::perMinute(5)->by($throttleKey)->response(function ($request, $params) {
                Log::info('User locked out due to too many login attempts.', ['request' => $request->input('email')]);
                $user = User::role('Super Admin')->first();
                $user->notify(new LockedOutUser($request->input('email')));
                return back()->withErrors([
                    'message' => "Too many login attempts. Please try again in {$params['Retry-After']} seconds"
                ]);
            });
        });
