After granting authority, copy the link that appears below the SCOPE frame to access it. Once accessed, select the location where you want to add the BOT and press Yes.

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

#Define an event handler to be executed when a message is sent
@client.event
async def on_message(message):
    if message.author.bot:
        pass
    elif message.content.startswith('Hello!'):
        send_message = f'{message.author.mention}San, Hello!'
        await message.channel.send(send_message)
