xbox partner center association

Hi, we are developing a game for XSX platform that requires multiplayer. The Microsoft partner center account is created by another organization and they have setup the game project. When I try to associate the UE5 project with the project in partner center (in XSX settings) I cannot see the appropriate option in the project list. It could be because the editor is using a wrong organization when connecting to partner center. Could you please advice how to associate the UE5 project with partner center in our case?

You need to use the XblDevAccount.exe tool that was delivered with the GDK!
