Imgui does not render, GLFWwindow is rendering just fine

// where window is created
m_Window = glfwCreateWindow((int)props.Width, (int)props.Height, m_Data.Title.c_str(), nullptr, nullptr);
glfwMakeContextCurrent(m_Window);

ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO();
// Setup Platform/Renderer bindings
ImGui_ImplGlfw_InitForOpenGL(m_Window, true);
ImGui_ImplOpenGL3_Init("#version 410");

I can't say it's not running because it is running, it just does not render at all, but does not throw any error/exceptions either.

System: Windows 10
IDE: MS Visual Studio 2022

I'm using
imgui_impl_opengl3.h/cpp
imgui_impl_glfw.h/cpp
imgui_impl_opengl3_loader.h
from folder 'backends'

Project builds and runs correctly, the window is working as expected, how do I my imgui show up?

Edit:
Solved, please close this discussion.
An advice for whoever later come across the same problem:
Make sure the swapBuffer always happen at the very end, otherwise imgui won't show up.
