* [messages.BotCallbackAnswer](messages.BotCallbackAnswer.md) - If the button is a keyboardButtonCallback or a keyboardButtonGame the button will be pressed and the result will be returned
*`false` - If the button is an unsupported button, like keyboardButtonRequestPhone, keyboardButtonRequestGeoLocation, keyboardButtonSwitchInlinekeyboardButtonBuy; you will have to parse data from these buttons manually
You can also access the properties of the constructor as a normal array, for example $button['name']
