How can I get my own referral code?

Hello there! I was wondering if you could help me out with something. I've been using your platform for a while now and I've been really enjoying it. However, I've seen some of my friends sharing their referral codes and earning rewards, and I was wondering how I can get my own referral code as well. Could you please guide me through the process? It would be great if you could provide me with a step-by-step explanation. Thanks in advance!
