reply_msg_idreply_msg_id, ignoring the topic ID), however, since message threads can't have nested message threads, topics (except for the "General" topic) also can't have message threads (so replies to messages within topics won't generate further message threads).
Topics have a name (title) and an icon: the icon can be a custom emoji specified by the icon_emoji_id, or a default chat icon if icon_emoji_id is not set, filled with the color specified in icon_color.
Topics can be temporarily closed, preventing further messages from being sent to the topic.
-Additionally, the "General" topic may also be hidden.
+Additionally, (only) the "General" topic may also be hidden.
All topics except for the "General" topic can be deleted by invoking channels.deleteTopicHistory, with the topic ID.
Topics can be created by using the channels.createForumTopic method, and may be modified with the channels.editForumTopic method: these actions require manage_topics rights, and will generate messageActionTopicCreate/messageActionTopicEdit service messages.
Note that Telegram Premium users can pass any custom emoji to icon_emoji_id, while other users can only use the custom emojis contained in the inputStickerSetEmojiDefaultTopicIcons emoji pack.
