I used glfw+dx12 to set ImGuiConfigFlags_ViewportsEnable ,but it did not work.

Here is my code.
{
// Setup Dear ImGui context
IMGUI_CHECKVERSION();
ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO(); (void)io;
io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard; // Enable Keyboard Controls
//io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad; // Enable Gamepad Controls
io.ConfigFlags |= ImGuiConfigFlags_DockingEnable; // Enable Docking

	//TODO: 
	io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable;         // Enable Multi-Viewport / Platform Windows


	// Setup Dear ImGui style
	ImGui::StyleColorsDark();
	//ImGui::StyleColorsClassic();
	// When viewports are enabled we tweak WindowRounding/WindowBg so platform windows can look identical to regular ones.
	ImGuiStyle& style = ImGui::GetStyle();
	if (io.ConfigFlags & ImGuiConfigFlags_ViewportsEnable)
	{
		style.WindowRounding = 0.0f;
		style.Colors[ImGuiCol_WindowBg].w = 1.0f;
	}

	Application& app = Application::Get();
	GLFWwindow* window = static_cast<GLFWwindow*>(app.GetWindow().GetNativeWindow());
	DX12 = &(Application::Get().GetDX12());
	


	
	ImGui_ImplDX12_InitInfo init_info = {};
	init_info.Device = DX12->d3dDevice.Get();
	init_info.NumFramesInFlight = DX12->swapChainDesc.BufferCount;
	init_info.RTVFormat = DX12->swapChainDesc.BufferDesc.Format;
	init_info.SrvDescriptorHeap = DX12->srvHeap.Get(); // 必须是 SHADER_VISIBLE 的 SRV Heap
	init_info.CommandQueue = DX12->cmdQueue.Get(); //主渲染队列
	static ExampleDescriptorHeapAllocator g_pd3dSrvDescHeapAlloc = DX12->g_pd3dSrvDescHeapAlloc;
	init_info.SrvDescriptorAllocFn = [](ImGui_ImplDX12_InitInfo*, D3D12_CPU_DESCRIPTOR_HANDLE* out_cpu_handle, D3D12_GPU_DESCRIPTOR_HANDLE* out_gpu_handle) { return g_pd3dSrvDescHeapAlloc.Alloc(out_cpu_handle, out_gpu_handle); };
	init_info.SrvDescriptorFreeFn = [](ImGui_ImplDX12_InitInfo*, D3D12_CPU_DESCRIPTOR_HANDLE cpu_handle, D3D12_GPU_DESCRIPTOR_HANDLE gpu_handle) { return g_pd3dSrvDescHeapAlloc.Free(cpu_handle, gpu_handle); };
	

	ImGui_ImplDX12_Init(&init_info);
	ImGui_ImplGlfw_InitForOther((GLFWwindow*)Application::Get().GetWindow().GetNativeWindow(), true);
}
