Interactive Message buttons not working

Hello There,

I'm having some issues with interactive buttons in a conversation.

I have copied everything relevant from botman studio and everything is working with the exception of buttons and menu list interactions.

When i click a button, i get by fallback message '' Sorry i don't understand that command " As apposed to responding with a joke or quote.

I'm sure i'm missing a configuration or something, but I can't for the life of me figure out what the issue is.

route/botman.php
```
hears('Hi', function ($bot) {
$bot->reply('Hello!');
});

$botman->hears('Start conversation', BotManController::class.'@startConversation');

$botman->fallback(function($bot) use ($actions) {
$bot->reply("Sorry i don't understand that command");
});
```
Botman controller
```
/**
* Place your BotMan logic here.
*/
public function handle(Request $request)
{
$botman = app('botman');
$botman->listen();
}

public function startConversation(BotMan $bot)
{
$bot->startConversation(new ExampleConversation());
}
```

Example conversation

```
fallback('Unable to ask question')
->callbackId('ask_reason')
->addButtons([
Button::create('Tell a joke')->value('joke'),
Button::create('Give me a fancy quote')->value('quote'),
]);

return $this->ask($question, function (Answer $answer) {
Log::info("Is interactive reply ? " . $answer->isInteractiveMessageReply());
$this->say("Is interactive reply ? " . $answer->isInteractiveMessageReply());
$this->say($answer->getValue());
if ($answer->isInteractiveMessageReply()) {
Log::info("Inside interactive message reply");
Log::Info("Answer value : " . $answer->value());
if ($answer->getValue() === 'joke') {
$responseContent = file_get_contents('http://api.icndb.com/jokes/random');
Log::info($responseContent);
$joke = json_decode($responseContent);
$this->say($joke->value->joke);
} else {
$this->say(Inspiring::quote());
}
}
});
}

/**
* Start the conversation
*/
public function run()
{
$this->askReason();
}
}
```

Start with route/botman.php, the controller's handle() and startConversation() methods, and ExampleConversation::askReason(), then reproduce the button interaction through botman->listen(). Done means the joke and quote buttons reach their intended branches instead of triggering the fallback message.
