discord.py , help command wont be disabled and still works

im trying to disable the help and create my own help but no matter how many times i tried , it didnt work
i tried client = commands.Bot(command_prefix = "$",help_command=None , intents = discord.Intents.all()) and tried client.remove_command('help') aswell but still no result and help still works

MY CODE :

@client.command()
async def help(ctx):
    
    emb = discord.Embed(description='⚠️ This Command doesnt work ,Try $helpme', color=0x0d67d6)
    await ctx.channel.send(embed=emb)
