UNREAL SOURCE CODE GDK?

Hello everyone, I apologize if I’m creating an unnecessary question, but here we go. I just joined Unreal because I intend to completely migrate from CONSTRUCT 2 and 3 to UNREAL since I’m limited when it comes to creating games for XBOX ONE, I have 2 games that I ported in UWP but it limits me a lot so now I’m trying UNREAL, but I I came across UNREAL SOURCE CODE and the XDK/GDK of the XBOX, I don’t know how to do it, in which folders and which folders of the GDK or XDK to put in which folders inside the UNREAL, could someone help me? Thanks.
