My simplified code:

username = ''
APP_SECRET = ''

class Bot(commands.Bot):
    def __init__(self):
        super().__init__(token=APP_SECRET, prefix='?', initial_channels=[username])

    async def event_message(self, message):

        chatter_user = await m.author.user()
        await chatter_user.delete_chat_messages(APP_SECRET, self.user_id, m.id)
