[vinbala]

Is your feature request related to a problem? Please describe.

'Timeout in milliseconds' property is not available in any of 'Ask a question' actions. Without this feature, we bot keeps on listening when there is no input from user. We are unable to implement loop/re-iterate capability.

Describe the solution you'd like

Provide 'Timeout in milliseconds' in 'Ask a question' actions. After the specified amount of milliseconds the dialog should complete with its default value if the user doesn't respond.

Describe alternatives you've considered

No alternate option available.
