Loading an external lib in an unreal c++ project

I am writing a class to load an external lib file using the function HINSTANCE hinstSHDOCLC =LoadLibrary(*filePath);
But using this I am getting the below errors. Also, I have included the following headers also.
#include “Misc/Paths.h”
#include “GenericPlatform/GenericPlatformProcess.h”
#include “HAL/FileManagerGeneric.h”
#include “Windows/WindowsPlatformProcess.h”

And also I tried to use this function to load the lib. But it cannot access as it is private.
m_dllHandle = FWindowsPlatformProcess::LoadLibraryWithSearchPaths(“ShapeToGeomGenerator.lib”, path);

What I can I do to load the library in win64 platform
