How to buy Xen on Trust Wallet?

Hello there, I'm curious about the process of purchasing Xen using Trust Wallet. Could you walk me through the steps in detail? I'm particularly interested in understanding how to navigate the app, select Xen as the cryptocurrency I want to buy, and complete the transaction securely. Also, is there anything I should be aware of before making the purchase, like fees or potential risks? I'd appreciate your guidance on this matter.
