May I ask how to make the Execution of the shader Synchronous so that it will block until the result is ready?

May I know how to achieve the following

#include "MyShaders/Public/MySimpleComputeShader.h"
 
FMySimpleComputeShaderDispatchParams Params(1, 1, 1);
 
Params.Input[0] = 2;
Params.Input[1] = 5;
 
// Block the thread until complete.
int OutputVal=FMySimpleComputeShaderInterface::Dispatch(Params);
