why is my discord.py command not working or sending messages

Question

I have this edit snipe command and event in which if a user edits a messages it snipes it. The event works fine and sends the edited messages into a private logs admin channel. However, when I try to make this into a command and it send an embed into the given command channel the message and command does not work at all

    @commands.command()
    async def es(self,message_before, message_after):
        embed=discord.Embed(description=f"📝**Message sent by** {author} **edited in** {channel}")
        embed.set_author(name= f" ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ {message_before.author.name}#{message_before.author.discriminator}")
        embed.add_field(name="Old message", value=message_before.content, inline=False)
        embed.add_field(name="New message", value=message_after.content, inline=False)
        await message_before.channel.send(embed=embed)
        return

You are confusing command and event .

In the previous answer by @Cohen in your other post , he told you to use the on_message_edit event. This event ( and many others ) are already defined by the discord.py library, hence they already provide the input parameters.

If you want to send an embed each time an user edits a message, do not do it in a separate function, add your code to the piece of code in on_message_edit . If, on another hand, you want to be able to call a command (" !es ") for example, who will retrieve the last edited message, you will need to create a database and keep a log of the edited messages (a single table with a old_message and new_message columns).

You can use DB Browser for SQLite to create and manually check your database, and I suggest using an asynchronous library such as aiosqlite which works well with discord.py
