-- | Creates a value of 'GetBuiltinIntents' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'gbiLocale' - A list of locales that the intent supports.
--
-- * 'gbiNextToken' - A pagination token that fetches the next page of intents. If this API call is truncated, Amazon Lex returns a pagination token in the response. To fetch the next page of intents, use the pagination token in the next request.
--
-- * 'gbiSignatureContains' - Substring to match in built-in intent signatures. An intent will be returned if any part of its signature matches the substring. For example, "xyz" matches both "xyzabc" and "abcxyz." To find the signature for an intent, see <https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/built-in-intent-ref/standard-intents Standard Built-in Intents> in the /Alexa Skills Kit/ .
--
-- * 'gbiMaxResults' - The maximum number of intents to return in the response. The default is 10.
