PlayFab Party OSS for UE4

I’m trying to use PlayFab Party OSS as a chat solution for my multiplayer project. But after I installed Microsoft GDK and copied plugin into my project, I cannot compile my solution anymore.

It said:
“The platform name XboxOneGDK is not a valid platform name. Valid names are (Win32,Win64,HoloLens,Mac,XboxOne,PS4,IOS,Android,HTML5,Linux,LinuxAArch64,AllDesktop,TVOS,Switch,Lumin)
while parsing PluginReferenceDescriptor OnlineSubsystemPlayFabParty”

Mybe standard UE does not support this. What can I do now?
