有些事如何做: discord.py deleting messages sent from webhook

I created a prank command in which I used a webhook to send msgs and the username of the member mentioned on the command, so it looks like the member itself sent that msg and I also included an emoji so it looks like the emojis was processed by NQN and therefore the msg had a bot tag..... but now I cannot understand how to delete that webhook msg using a command. can anyone help me in that command
