【Instructions for use】
・For beginners who are not good at setting permissions, administrator rights are requested at the time of installation, but this can be eliminated
・When you send a chat message that includes a message link, the bot will retrieve the link and display the quoted message.
・The Bot will not respond to links enclosed in half-width "<>" characters. <> will be invisible after the message is sent.
・When you select "jump" in the bot's message, the bot jumps to the original message.
・If the person who sent the link or the original poster responds to the bot message with ❌, the message will be deleted. This function is useful when you want to erase a bot message that was mistakenly sent or a past statement.

【Main Features】
・No functions other than citation
・Attachments other than images are supported.
・The URL can be erased after quoting because the link of the original statement and the name of the quoted person are included.
・When quoting multiple images or Embedded comments, they are sent together.
→The remarks of others are not interspersed in between, making them difficult to read.
・When you quote by mistake, you can delete it even if you do not have the authority to manage messages.
・Can be used in threads and VC-attached text.
