Почему бот игнорирует команду?

Question

[Ruslan_Kochiev]

import disnake
from disnake.ext import commands

intents = disnake.Intents.all()
bot = commands.Bot(command_prefix='!', intents=intents)


bot = commands.Bot(command_prefix=".", help_command=None, intents=disnake.Intents.all())
@bot.command()
async def ping(ctx):
    await ctx.send("pong!")
