+    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 telegram.me/your_bot?start=XXXX that open your bot with a parameter.

+    :param token: Bot's token (you don't need to fill this)
+    :param callback_query_id: Unique identifier for the query to be answered
+    :param text: (Optional) Text of the notification. If not specified, nothing will be shown to the user, 0-200 characters
+    :param show_alert: (Optional) If true, an alert will be shown by the client instead of a notification at the top of the chat screen. Defaults to false.
+    :param url: (Optional) 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.
+    Otherwise, you may use links like telegram.me/your_bot?start=XXXX that open your bot with a parameter.
+    :param cache_time: (Optional) 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.
