-- | Creates a value of 'GetIntentResponse' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:

-- * 'girsFulfillmentActivity' - Describes how the intent is fulfilled. For more information, see 'PutIntent' .
--
-- * 'girsSlots' - An array of intent slots configured for the intent.
--
-- * 'girsRejectionStatement' - If the user answers "no" to the question defined in @confirmationPrompt@ , Amazon Lex responds with this statement to acknowledge that the intent was canceled.
--
-- * 'girsChecksum' - Checksum of the intent.
--
-- * 'girsConclusionStatement' - After the Lambda function specified in the @fulfillmentActivity@ element fulfills the intent, Amazon Lex conveys this statement to the user.
--
-- * 'girsSampleUtterances' - An array of sample utterances configured for the intent.
--
-- * 'girsParentIntentSignature' - A unique identifier for a built-in intent.

-- * 'girsFollowUpPrompt' - If defined in the bot, Amazon Lex uses this prompt to solicit additional user activity after the intent is fulfilled. For more information, see 'PutIntent' .
--
-- * 'girsLastUpdatedDate' - The date that the intent was updated. When you create a resource, the creation date and the last updated date are the same.
--
-- * 'girsConfirmationPrompt' - If defined in the bot, Amazon Lex uses prompt to confirm the intent before fulfilling the user's request. For more information, see 'PutIntent' .
