Run ping command in discord.py

I know it has been solved like a million of times, but none of the current answers can help me.

This is how I configured the bot:

import discord
from discord.ext import commands
    
bot = commands.Bot(intents=discord.Intents.all(), command_prefix="-", description="A simply well made bot...")

and this is the command's code:

@bot.command()
async def ping(ctx):
    await ctx.send(f'Pong! In {round(bot.latency * 1000)}ms')
