How do I activate my XCP license?

Excuse me, could you please explain the steps involved in activating my XCP license? I've been trying to do it on my own, but I'm a bit confused about the process. Is there a specific website or platform I need to use? Do I need to provide any personal information or verification documents? Also, is there a fee associated with activating the license? I would really appreciate your guidance on this matter. Thank you.
