@client.event
async def on_message(message):

    channels = ['bot-commands']
    if str(message.channel) in channels:
        if message.content == '!help':
            embed = discord.Embed(title='How to use the ImposterBot', description='Useful Commands')
            embed.add_field(name='!help', value='Display all the commands')
