RHICreateTexture2D is not available in UE 5.3?

It seems RHICreateTexture2D does not exist any more in UE5.3? I cannot find it in doc.
How should I update the following code to UE5?

void ASceneVideoCapture::OnBackBufferReady_RenderThread(SWindow& SlateWindow, const FTexture2DRHIRef& BackBuffer)
{
	FTexture2DRHIRef GameBuffer = BackBuffer;

	FRHIResourceCreateInfo CreateInfo(TEXT("Texture"));
	FRHITextureCreateDesc TextureCreateDesc = FRHITextureCreateDesc::Create2D(TEXT("TextureOfCopy"), GameBuffer->GetSizeX(), GameBuffer->GetSizeY(), GameBuffer->GetFormat());
	FTexture2DRHIRef CopiedTexture = RHICreateTexture2D(
		GameBuffer->GetSizeX(),
		GameBuffer->GetSizeY(),
		GameBuffer->GetFormat(),
		GameBuffer->GetNumMips(),
		GameBuffer->GetNumSamples(),
		ETextureCreateFlags::CPUReadback,
		CreateInfo
	);
	FRHICommandListImmediate& RHICmdList = FRHICommandListExecutor::GetImmediateCommandList();
	RHICmdList.CopyTexture(GameBuffer, CopiedTexture, FRHICopyTextureInfo{});

	void* RawData = nullptr;
	int32 Width = 0, Height = 0;
	RHICmdList.MapStagingSurface(CopiedTexture, RawData, Width, Height);

       // ...
	RHICmdList.UnmapStagingSurface(CopiedTexture);
}

Ok, I find the answer by myself.

FTexture2DRHIRef GameBuffer = BackBuffer;
FRHICommandListImmediate& RHICmdList = FRHICommandListExecutor::GetImmediateCommandList();

FRHITextureCreateDesc TextureCreateDesc = FRHITextureCreateDesc::Create2D(TEXT("CopiedTexture"),
	GameBuffer->GetSizeX(),
	GameBuffer->GetSizeY(),
	GameBuffer->GetFormat());
TextureCreateDesc.SetNumMips(GameBuffer->GetNumMips());
TextureCreateDesc.SetNumSamples(GameBuffer->GetNumSamples());
TextureCreateDesc.SetInitialState(ERHIAccess::CPURead);
TextureCreateDesc.SetFlags(ETextureCreateFlags::CPUReadback);
FTextureRHIRef CopiedTexture = GDynamicRHI->RHICreateTexture_RenderThread(RHICmdList, TextureCreateDesc);

RHICmdList.CopyTexture(GameBuffer, CopiedTexture, FRHICopyTextureInfo{});

void* RawData = nullptr;
int32 Width = 0, Height = 0;

RHICmdList.MapStagingSurface(CopiedTexture, RawData, Width, Height);

RHICmdList.UnmapStagingSurface(CopiedTexture);
