There is a text channel where several messages are written from the bot, how they can be deleted by a script through the same bot, I don’t understand this much, so I decided to try to find help here.
It doesn't matter which way, you can even delete by id or delete one last message

Answer 1

fetch messages, brute force if author is equal to bot = delete
