ctx is a required argument

I am trying to make a simple music bot. When I execute the command I get this error: discord.ext.commands.errors.MissingRequiredArgument: ctx is a required argument that is missing.

This is my code:

import discord
from discord.ext import commands

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

class VoiceConnectionError(commands.CommandError):
    """Custom Exception class for connection errors."""
    ...

class InvalidVoiceChannel(VoiceConnectionError):
    """Exception for cases of invalid Voice Channels."""
    ...

@bot.event
async def on_ready():
    print('Bot ready')

@bot.command(name='connect', aliases=['join'])
async def connect(self, ctx, *, channel: discord.VoiceChannel=None):
    await ctx.send(f'Connected to: **{channel}**', delete_after=10)


bot.run('TOKEN')

The command should move the bot into the voice channel in discord.

This is the full traceback:

Your commands should only accept a self parameter if they are part of a cog. Remove the parameter:

@bot.command(name='connect', aliases=['join'], pass_context=True)
async def connect(ctx, *, channel: discord.VoiceChannel=None):
    ...
