Help me understand

well i want to play with ImGui and it seems that it doesnt work by itself, like it need some window to connect to. So I added ClickableTransparentOverlay package and now ImGui magicly working even thought I didnt write any "connection" code between ImGui and ClickableTransparentOverlay window. So my question is how does ImGui knows to which window it should connect?

code that I wrote

using ClickableTransparentOverlay;
using ImGuiNET;

var window = new CustomOverlay();
await window.Run();

internal class CustomOverlay : Overlay
{
    public CustomOverlay() : base(1920, 1080)
    {
    }

    protected override void Render()
    {
        ImGui.Begin("Test");
        ImGui.Text("Works");
    }
}

using ClickableTransparentOverlay;
using ImGuiNET;

var window = new CustomOverlay();
await window.Run();

internal class CustomOverlay : Overlay
{
    public CustomOverlay() : base(1920, 1080)
    {
    }

    protected override void Render()
    {
        ImGui.Begin("Test");
        ImGui.Text("Works");
    }
}

Internally ClickableTransparentOverlay calls ImGui.CreateContext() and after your code in Render is executed it internally calls another render method that takes the drawn bitmap from ImGui and draws it to a DX11 device
