-- | Returns messages in a topic in a forum supergroup chat or a chat with a bot with topics. The messages are returned in reverse chronological order (i.e., in order of decreasing message_id). For optimal performance, the number of returned messages is chosen by TDLib. Returns 'TD.Data.Messages.Messages'
