How do I withdraw bitcoins from vault?

I'm curious about withdrawing my bitcoins from the vault. Could you walk me through the process, step-by-step? I'd like to understand what precautions I should take to ensure the safety of my funds, and if there are any fees associated with the withdrawal. Additionally, how long does the withdrawal process typically take, and is there a limit to the amount of bitcoins I can withdraw at once? It would be great if you could provide some clarity on these questions to help me make an informed decision.
