How do I get my money from CEX?

Hello there, I'm curious about something regarding cryptocurrency exchanges. I've been trading on a CEX platform and have accumulated some funds there. However, I'm a bit unsure about how to withdraw my money from the platform. Could you guide me through the process? What steps should I follow to ensure a smooth and secure withdrawal? Are there any fees involved? Additionally, how long does it typically take for the funds to reach my bank account or cryptocurrency wallet? Thank you in advance for your help.
