When creating an Azure Web Bot, one of the default Web Chat clients is a fork of microsoft's [BotBuilder-Samples][1] project, specifically [49 - QnAMaker All Features][2]

The source code for `Dialog/QnAMakerBaseDialog.cs` defines the constant [`DefaultNoAnswer`][3]:

```cs
public const string DefaultNoAnswer = "No QnAMaker answers found.";
```

And then uses that value when returning a response from [`GetQnAResponseOptionsAsync`][4]:

```cs
protected async override Task<QnADialogResponseOptions> GetQnAResponseOptionsAsync(DialogContext dc)
{
    var noAnswer = (Activity)Activity.CreateMessageActivity();
    noAnswer.Text = DefaultNoAnswer; // <- used right here

    var cardNoMatchResponse = (Activity)MessageFactory.Text(DefaultCardNoMatchResponse);
           

    var responseOptions = new QnADialogResponseOptions
    {
        ActiveLearningCardTitle = DefaultCardTitle,
        CardNoMatchText = DefaultCardNoMatchText,
        NoAnswer = noAnswer,
        CardNoMatchResponse = cardNoMatchResponse,
    };

    return responseOptions;
}
```

This particular sample repo doesn't appear to leverage the `DefaultAnswer` configuration key anywhere.

You can opt to include it when available by updating the `noAnswer.Text` like this:

```diff
- noAnswer.Text = DefaultNoAnswer;
+ noAnswer.Text = this._configuration["DefaultAnswer"] ?? DefaultNoAnswer;
```

You'll also have to pass in the configuration object through the dependency management system. See [this commit][5] for a full example.

I want change Default Answer in Q&A Maker Azure Framework Bot, but I cant find field that respond this value. I'm reading documentation (but it looks like it uses an older interface), and I'm trying to find this field but with result.

Here's my current configuration screen:
