You can preview your Virtual Human in the Conversation editor as you create it, to make sure it is working the way you expect.
To test any Conversation, open it up in the portal, and then click the button to Test Widget Now. An overlay will appear in your portal window where the widget will load. Once it has loaded you will see an icon appear. Click the icon to take you through the current Conversation.
If changes are needed then exit the test widget and update your Conversation. Don't forget to Save Changes!
