Help with discord configuration please

Hello im trying to create an automation to turn a fan off in my sons room when he gets onto discord with me. The fan blows in the background making horrible noises. Is this possible with the discord bot or is this only for sending messages to discord from home assistant?

I went through the setup as per the instructions but when it says to put a check next to OAUTH2 it wont authorize the bot, so i clicked public bot and it authorized and now im able to send messages to discord from home assistant. I see the bot is always offline in discord though.

So basically OAUTH2 didnt work, and i need to know if i can be notified when a user joins my channel?

Thanks for the help guys and gals
