I was copying the code and everything from
But they said nothing about how shall I fill the .env file.
Just to clear everything.

In my .env file TMI_TOKEN is oauth from Twitch Chat Password Generator
CLIENT_ID is Client_id in my app in twitch dev
BOT_NICK is just a name and I can set it to whatever I want
CHANNEL is my twitch account
Is it like that? If it is, okay, I’ll close this topic if I can and just go try it one more time and go trying to solve the problem by my own.
