How to buy Dione in Trust Wallet?

Could you please explain the process of purchasing Dione tokens through the Trust Wallet application in detail? I'm interested in knowing the steps required, including whether I need to enable any specific features or connect to any external exchanges. Additionally, is there a recommended minimum amount of Dione to purchase, and are there any associated fees I should be aware of? Lastly, how do I ensure the safety of my funds during and after the transaction?
