Source Code integration link broken for PS5 port

Hi, we have recveived the email confirmation for access to Unreal Source Code within the following link:

https://www.unrealengine.com/en-US/ue-on-github

We have also linked apps and accounts from www.epicgames.com/account/connection to both Playstation and Github, but according to the following instructions we are supposed to get a link for integration that is broken, or cannot be accessed.

This is the link: https://udn.unrealengine.com/s/

Could you please point us in the right direction to finally get the source code for PS5 up and running on our version of Unreal Engine?

Regards!
