Discord.py Why will this client.command not work?

Question

import discord
from discord.ext import commands
import asyncio

client = commands.Bot(command_prefix="-")

@client.event
async def on_message(message):
    if message.content.startswith("uno regeln"):
        await message.channel.send('http://www.uno-kartenspiel.de/spielregeln/')        

@client.command()
async def test(ctx):
    await ctx.send("Ok")
     
client.run("TOKEN")

When I try to run this and use -test nothing happens But why? I looked in the docs but in my opinion everything is fine

Answer 1

As given by the link provided by @Lukasz Kwieciński, you need to change it to:

import discord
from discord.ext import commands
import asyncio

client = commands.Bot(command_prefix="-")

@client.event
async def on_message(message):
    if message.content.startswith("uno regeln"):
        await message.channel.send('http://www.uno-kartenspiel.de/spielregeln/')        
    await bot.process_commands(message)
@client.command()
async def test(ctx):
    await ctx.send("Ok")
     
client.run("TOKEN")

Answer 2

import discord
from discord.ext import commands

intents = discord.Intents.default()
client = commands.Bot(command_prefix="!", intents=intents)
client.remove_command('help')

@client.event
async def on_ready():
    print("Bot Is Ready")
    
    await client.change_presence(activity=discord.Game(name="TYPE THERE ANYONE"))

@client.command()
async def test(ctx):
    await ctx.send("Ok")

client.run('YOUR TOKEN')

Try this
