How to initialize FRDGBuffer from cpu

Hello.
I would like to use a Buffer for delivering an array of floats from cpu into a shader.
I have no idea how to initialize it with the cpu data array.

Here is the code I did up to now:

shader side:

Buffer<float> myArray;

cpp side:

BEGIN_SHADER_PARAMETER_STRUCT(MyParamateres, )
          :
	SHADER_PARAMETER_RDG_BUFFER_SRV(Buffer<float>, myArray)
          :
END_SHADER_PARAMETER_STRUCT()


static void prepare_data_for_rendering(TArray<float>& data) 
{
  // create GPU buffer
  FRDGBufferDesc TestBufferDesc = FRDGBufferDesc::CreateBufferDesc(sizeof(float), data.Num());
  FRDGBuffer* pBuffer = GraphBuilder.CreateBuffer(TestBufferDesc, TEXT("MyParamateres.myArray"));
  // create Shader Resource View (read) for the buffer for reading it within the shader stage
  MyParamateres.myArray= GraphBuilder.CreateSRV(pBuffer , PF_R32_FLOAT);


 // ???  how to initialize pBuffer with data ???

}
