How to create an Unknown Story
In order to obtain reliable statistics, it is necessary to create an "Unknown story". The "Unknown story" allows to determine the response of the bot when it does not understand the user request. Moreover, being a story, it allows to internationalize this answer.
To create an "Unknown story" in your bot:

1. Go to "Stories & Answers" then "New story" tab.
2. Give a name to your "Unknown story" (for example: Unknown Story) then validate
3. Click on the "Edit story" icon and in the "Intent" field, enter the word "unknown"
4. In the "Answers" part, enter the message to return to users when the bot does not understand their request.
5. Click on "Create story"
