FJsonObjectConverter::UStructToJsonObjectString(...) How to skip any properties. Dont add this properties to result json

Hello!
I try to understand how to skip any of properties from my USTRUCT structure and dont write this properties to result json file.
I use

“bool
FJsonObjectConverter::UStructToJsonObjectString(const
UStruct* StructDefinition, const void*
Struct, FString& OutJsonString, int64
CheckFlags, int64 SkipFlags, int32
Indent, const CustomExportCallback*
ExportCb, bool bPrettyPrint)”

method to generate json! But i dont understand how to skip, for example, not filled TArray. UStructToJsonObjectString(…) have “SkipFlags”, but i cant find examles how to use this SkipFlags. All examples of using UStructToJsonObjectString(…) haves only 0 in this variable.
Sorry for my english.

This has to do with EPropertyFlags
