If I win, how do I actually get the money?

Let’s say I play and actually win. And let’s even say I find my result in the list. What’s next? Do I have to message someone or will someone contact me, or do I have to leave a request somewhere? Honestly, I don’t get how the whole winning process works. Of course, if I ever actually win.

 

From what I imagine, you just report that you have a winning ticket on the official lottery site. And show proof. I’ve never actually done it myself, so no personal experience. But if, like I’ve heard, you don’t need to register on lottery sites, then how would they even know you won unless you tell them?
