How to make my Native Plugin show "GC.Alloc" in Profiler Hierarchy

According to https://docs.unity3d.com/Manual/LowLevelNativePluginProfiler.html, I add ProfilerMarker API to my cpp library, but It's hard to analyze the native memory allocation of it bzc I don't know how to make my custom data display in Profiler Panel as I wish.

// Available since 2020.1

UNITY_DECLARE_INTERFACE(IUnityProfiler)

{

    void BeginSample(const UnityProfilerMarkerDesc* markerDesc)

    {

        (this->EmitEvent)(markerDesc, kUnityProfilerMarkerEventTypeBegin, 0, NULL);

    }



    void BeginSample(const UnityProfilerMarkerDesc* markerDesc, uint16_t eventDataCount, const UnityProfilerMarkerData* eventData)

    {

        (this->EmitEvent)(markerDesc, kUnityProfilerMarkerEventTypeBegin, eventDataCount, eventData);

    }



    void EndSample(const UnityProfilerMarkerDesc* markerDesc)

    {

        (this->EmitEvent)(markerDesc, kUnityProfilerMarkerEventTypeEnd, 0, NULL);

    }



    void(UNITY_INTERFACE_API * EmitEvent)(const UnityProfilerMarkerDesc* markerDesc, UnityProfilerMarkerEventType eventType, uint16_t eventDataCount, const UnityProfilerMarkerData* eventData);



    int(UNITY_INTERFACE_API * IsEnabled)();

    int(UNITY_INTERFACE_API * IsAvailable)();



    int(UNITY_INTERFACE_API * CreateMarker)(const UnityProfilerMarkerDesc** desc, const char* name, UnityProfilerCategoryId category, UnityProfilerMarkerFlags flags, int eventDataCount);

    int(UNITY_INTERFACE_API * SetMarkerMetadataName)(const UnityProfilerMarkerDesc* desc, int index, const char* metadataName, UnityProfilerMarkerDataType metadataType, UnityProfilerMarkerDataUnit metadataUnit);



    int(UNITY_INTERFACE_API * RegisterThread)(UnityProfilerThreadId* threadId, const char* groupName, const char* name);

    int(UNITY_INTERFACE_API * UnregisterThread)(UnityProfilerThreadId threadId);

};

I have tried 'SetMarkerMetadataName' but It just change the Metadata formation from "0:44" to "Size:44".What should I do to make My UnityProfilerMarkerDesc display native memory allocation just like C# managed memory allocation.

 

Thanks, I got the Header.(named IUnityMemoryManager.h right?) I'll try it in new version Unity later. Maybe it's a good chance to try new ECS,either.
