Hello,
I'm currently trying to restrict registration so that only people with a specific invitation code can register.
ChatGPT suggested implementing a check for the invitation code, but I’m unable to locate the relevant check or controller PHP files.


Could you please advise where I should add this code? or if you know any better solution.
Thank you!
