for ue5.4 i use https://github.com/j05hau/UE5-SimpleUGC, forked from TheHellcat
I took the plugin from the UE5-SimpleUGC-main/Plugins folder and threw it into the folder with my 5.4 project
for someone who dont know (like me) how recompile SimpleUGC on Unreal Engine 5.4 - try to add #include "Features/IPluginsEditorFeature.h"
in SimpleUGC\Source\SimpleUGCEditor\PrivateSimpleUGCPluginWizardDefinition.cpp bc here u have some issue, and try recompile
maybe this will be helpful to someone
