Tried:
UFunction* Reference;
UClass* Refer = UK2Node_CallFunction::StaticClass();
Reference = Refer->FindFunctionByName(“Create Blueprint”);
class UBlueprintFunctionNodeSpawner* Spawner;
FVector2D Slerp;
Slerp.Set(0.f, 0.f);
FBlueprintActionMenuItem(Spawner->Create(Reference, nullptr)).PerformAction(Graph, nullptr, Slerp, false);

But get error:LNK2019 unresolved external symbol “__declspec(dllimport) public: __cdecl FBlueprintActionMenuItem::FBlueprintActionMenuItem(class UBlueprintNodeSpawner const *)” (_imp??0FBlueprintActionMenuItem@@QEAA@PEBVUBlueprintNodeSpawner@@@Z) referenced in function “public: static void __cdecl UMakeBlueprintNodeBPLibrary::AddNodeToBlueprint(class UEdGraph *)” (?AddNodeToBlueprint@UMakeBlueprintNodeBPLibrary@@SAXPEAVUEdGraph@@@Z) GeoNodesToGeoScript
