How to transfer money from bank to Wirex?

Can you walk me through the process of transferring money from my bank account to Wirex? I'm not very familiar with cryptocurrency exchanges and would appreciate a step-by-step guide. Specifically, I'm wondering if I need to set up a special account with Wirex or if I can use my existing bank account details. Also, what are the fees associated with the transfer, and how long does it typically take for the funds to arrive in my Wirex account? Additionally, are there any security measures I should be aware of to ensure the safety of my funds during the transfer process?
