How to modified the solution I had submitted

It’s been less than 30 minutes since I claimed the certificate that I realized an error I made.
Indeed, by mistake, the link submitted for the “Build a Product Landing Page”***
is the same as for the “Build a Technical Documentation Page”***. I want to change it because I have already claimed the certificate, I made this unfortunate error in good faith, and I don’t want to be penalized for it. Especially since the real solution is available.
So how can I change the URL submitted to correct it?
Thank you in advance.

***Build a Technical Documentation Page :

You can just go back and submit the project again with the new link.

Dear JeremyLT,
It works.
Thank you.
