How to buy ICO using Trust Wallet?

I'm a beginner in the crypto world and have heard a lot about Initial Coin Offerings (ICOs). I'm particularly interested in purchasing an ICO using Trust Wallet, as I've found it quite user-friendly. However, I'm a bit unsure of the exact steps involved. Could you guide me through the process of how to buy an ICO using Trust Wallet? What are the necessary prerequisites? Should I be concerned about any risks associated with investing in an ICO? Additionally, are there any specific tokens or projects that you would recommend I look into? I'd appreciate any advice or insights you could provide.
