How to withdraw from OKX wallet?

Could you please explain the process for withdrawing funds from an OKX wallet in detail? I'm particularly interested in knowing the steps to initiate a withdrawal, any verification requirements, and the estimated time frame for the funds to arrive in my designated account. Additionally, are there any fees associated with the withdrawal process, and if so, how are they calculated? Lastly, what security measures does OKX have in place to ensure the safety of my funds during the withdrawal process?
