    @commands.Cog.listener()
    async def on_message(self, message: discord.Message):

Can you try with discord.Cog? Also, are you using commands.Bot or discord.Bot?

Seems like this only happens when using discord.Bot, as it does not implement add_listener. commands.Bot however does implement add_listener and it works without issues.

should they be implemented into discord.Bot?

This is more of a bug, considering discord.Cog.listener is implemented but only works with commands.Bot.

I agree, just didn't want to work on something that may not be merged. cause how was this not caught in discord.py originally lol

discord.Cog does not exist in discord.py
