How to delete msg + 1?

[EMPTYyYyYyY]

Hi, guys! Thanks in advance more for your work, I decided to rewrite my bot after the Discord API stopped working.
Question: How can I delete using the command I created the command message or how many previous messages I want + text when I wrote the command in the chat.

Еxample(as it was before):

@commands.command()
    async def clear(self, ctx, amount: int):  
        messages = await ctx.channel.purge(limit=amount + 1)

Еxample(now):

async def clear(ctx):
     msg = await ctx.send("удалить это сообщение")
     await msg.delete()

but it only deletes the message I sent, and I just want the command to delete the messages. please tell me how you can implement my old example.
if you show the code with the implementation, I will be the happiest person in the world.

async def clear(ctx, amount: int):
    await ctx.channel.purge(limit=amount+1)
