Comments under channel posts are technically threads in the associated discussion group. When a user clicks "comments" under a post, they enter a separate thread in that group. All messages posted under the post are stored in that thread, and Telegram displays them in both the group and directly under the post for convenience.

If the bot replies "in the comment under the post", it is actually writing in the linked thread within the discussion group. Therefore, the bot’s message is visible both in the group and directly under the channel post. 

1. A channel subscriber can write a message by clicking "Leave a Comment" under a post or directly in the discussion group – replying to another message in the thread.

2. For each conversation thread, we create a separate group chat.

3. In the first message of such a chat, the post text is quoted before the user's message, and a link to the post is provided.

If the post is longer than 300 characters, we'll display only the beginning so you can quickly understand the topic, while ensuring the original message doesn't take up too much space in the conversation.

4. When a new chat is created from a comment under a channel post, we add the channel name, post ID, and user message text to the subject.

• Each thread under a post is a separate case on the Deskie side. If there is no chat for the thread yet or the previous such chat is in the "closed" status, a new chat will be created.
• If a subscriber writes directly to the group but not as a reply to any message from the thread, such a message will be processed on the Deskie side as a group chat message. More details
• It is possible to distinguish a comment on a post from a message in the discussion group by the case subject: in the first scenario, it will include the channel name, and in the second — the group name.
