How do I withdraw crypto from my exchange account?

Good afternoon, I'm curious about the process of withdrawing cryptocurrency from my exchange account. Could you please elaborate on the steps involved? I've heard there's some verification process, but I'm not sure what that entails. Also, are there any fees associated with withdrawing crypto? And how long does the withdrawal process typically take? I'd appreciate any insights you could provide to help me navigate this process smoothly. Thank you for your time and assistance.
