博特曼Laravel除介绍性消息外，未在laravel中回复

如何解决博特曼Laravel除介绍性消息外，未在laravel中回复

控制器：

?PHP
   namespace App\Http\Controllers;
  use BotMan\BotMan\BotMan;
  use Illuminate\Http\Request;
 use BotMan\BotMan\Messages\Incoming\Answer;
 class chatbotController extends Controller
   {
 public function handle()
{
    $botman = app('botman');
    $botman->hears('hi',function($bot) {
        $this->askName($botman);
    });
    $botman->hears('{message}',function($botman,$message) {           
        if ($message == 'Something electronic like a phone or TV') {
            $this->tree1($botman);
        }elseif($message == 'A trip to my favorite destination'){
            $this->tree2($botman);
        }
        elseif($message == 'Something else'){
            $this->tree3($botman);
        }
    }); 
         }
          public function tree1($botman)
      {
      $botman->ask('Choose 1: a)Phone. /n b) TV /n c) something else',function(Answer $answer) {
        $category = $answer->getText();
    }

视图为：

  <!doctype html>
     <html>
<head>
    <Meta charset="utf-8">
    <Meta name="viewport" content="width=device-width,initial-scale=1">
    <title>Myffer chatbot</title>
    <script src='https://cdn.jsdelivr.net/npm/botman-web-widget@0/build/js/widget.js'></script>
  
</head>
<body>
</body>

 <script>
    var botmanWidget = {
        aboutText: 'Myffer',introMessage: "Hi,how are you. My name is Matt and I will make sure you get the best 
 possible deal. Tell me,which type of product you are looking for?"
    };
     </script>

     </html>

这发送介绍性消息，然后不回复？我也想添加一些条件语句。像bot给出2个选项，然后单击其中一个bot会显示消息并询问其他问题我对laravel和botman还是陌生的。
