How to convert FDUSD to USD?

Could you please explain to me the process of converting FDUSD to USD? I've been trying to figure it out for a while, but I'm still a bit confused. Could you walk me through the steps involved? Are there any specific platforms or exchanges that I should use? Also, are there any fees or commissions that I should be aware of? It would be great if you could provide some clarity on this matter. Thank you in advance for your help!
