That widget has no settings for Twilio anywhere!!!

I checked the widget and indeed, there is no where to enter the auto token or credentials.  I will forward this to our developers to have a look.  We will let you know as soon as we have any updates.

In the mean time, you can enter credentials when using the old form builder.  While editing your form, reload the form from this URL:

The settings will be available from the fields properties menu:

You should be able to see them now under the international option.
