A confirmation is the message sent by the bot to confirm that it has understood the user's Intent.
Confirmations are used to reply to user inputs and help move the conversation forward. You can provide a set of messages that the bot will use when there is an user input.
You can provide the initial confirmation message when creating an intent.
Working with confirmations
Once you have added a confirmation message when creating the intent, you can then add more such messages, modify existing messages, or remove them.
