  , answerCallbackQueryShowAlert :: Maybe Bool -- ^ If True, an alert will be shown by the client instead of a notification at the top of the chat screen. Defaults to false.
  , answerCallbackQueryUrl :: Maybe Text
    -- ^ URL that will be opened by the user's client. If you have created a Game and accepted the conditions via @Botfather, specify the URL that opens your game — note that this will only work if the query comes from a callback_game button.

  , answerCallbackQueryCacheTime :: Maybe Integer -- ^ The maximum amount of time in seconds that the result of the callback query may be cached client-side. Telegram apps will support caching starting in version 3.14. Defaults to 0.

-- | Use this method to send answers to callback 
--   queries sent from inline keyboards. The answer 
--   will be displayed to the user as a notification 
--   at the top of the chat screen or as an alert. 
--   On success, True is returned.

--  Alternatively, the user can be redirected to 
--  the specified Game URL. For this option to work, 
--  you must first create a game for your bot via 
--  @Botfather and accept the terms. Otherwise, you 
--  may use links like t.me/your_bot?start=XXXX that 
--  open your bot with a parameter.
