 	 * Use this method to receive incoming updates using long polling.
 	 * This method will not work if an outgoing webhook is set up.
 	 * In order to avoid getting duplicate updates, recalculate offset after each server response.
 	 * @param offset Optional. Identifier of the first update to be returned. Must be greater by one than the highest among the identifiers of previously received updates. By default, updates starting with the earliest unconfirmed update are returned. An update is considered confirmed as soon as getUpdates is called with an offset higher than its update_id.
 	 * @param limit Optional. Limits the number of updates to be retrieved. Values between 1—100 are accepted. Defaults to 100.
 	 * @param timeout Optional. Timeout in seconds for long polling. Defaults to 0, i.e. usual short polling.
+	 * @param allowed_updates Optional. List the types of updates you want your bot to receive. For example, specify [“message”, “edited_channel_post”, “callback_query”] to only receive updates of these types. See Update for a complete list of available update types. Specify an empty list to receive all updates regardless of type (default). If not specified, the previous setting will be used.
