Discord gateway intents and the privileged three
What gateway intents control, which three are privileged, and the 10,000-user threshold at which Discord reviews access to them.

Discord bot permissions reference
Discord bot permissions — what each one grants, which are dangerous, how the bitfield works, and why the permission you granted is not the one it has.
