laravel : model events and streamed responses

what is the correct way of catching model events and sending them to the browser as push notification. Basically what i want is to send notifications(SSE) to the browser when a new notification is created for a user. Currently i'm using Symfony StreamedResponse in the following method in a controller and it's not working.

'Notification' is an eloquent model having a 'user_id' field.

/* Notification Controller Stream method */
public function stream() {
    if(Auth::check()) {
        $user = Auth::user();
        $response = new StreamedResponse(function() use ($user) {
            Notification::created(function($notification) use ($user) {
                if($notification->user_id == $user->id) {
                    echo "notification:" . json_encode(['notification' => $notification]) . "\n\n";
                    ob_flush();
                    flush();
                }
            });
        $response->headers->set('Content-Type', 'text/event-stream');
        return $response;
    }
    return 'Not logged in.';
}

If it helps : When i visit this method through its URL, the browser never starts loading. It ends up in an infinite loop. What am i doing wrong here? Any help is much appreciated.
