How to trade Wirex?

So, I'm curious about trading with Wirex. Can you walk me through the basics of how it works? Do I need to set up an account first? How do I fund my account and start trading? Is there a specific platform or app I need to use? And how do I go about buying and selling cryptocurrencies with Wirex? Any tips or advice for beginners like myself? I'd appreciate any insights you can offer.
