discord bot: client.start(Token) not working

Question

trying to run a discord bot

this is the code

import discord
from discord.ext import commands

TOKEN: str = "Token"

client = commands.Bot(command_prefix = '.')

@client.event
async def on_ready():
    print('Connected')

client.start(TOKEN)

I get this error:

C:\Users\josep\AppData\Local\Programs\Python\Python38\python.exe C:/Users/josep/Desktop/unsettler/unsettler.py
C:/Users/josep/Desktop/unsettler/unsettler.py:12: RuntimeWarning: coroutine 'Client.start' was never awaited
  client.start(TOKEN)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

I tried using client.run instead of client.start, but it triggers more errors. How do I fix this?

edit: the errors I got from client run:

Traceback (most recent call last):
  File "C:\Users\josep\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\http.py", line 291, in static_login
    data = await self.request(Route('GET', '/users/@me'))

    raise HTTPException(r, data)
discord.errors.HTTPException: 401 Unauthorized (error code: 0): 401: Unauthorized

The above exception was the direct cause of the following exception:

According to the traceback for client.run, the RuntimeError at the bottom was derived from this exception:

LoginFailure('Improper token has been passed.')

Essentially, check that you copied the correct token into the TOKEN variable. When you go to the developer portal and click on your application, make sure that you copy the bot token (you will find it in the Bot tab on the left) and not the client secret or client ID.
