Detect raw mouse events

Unity Engine

Hello everyone,
I am working on an eyedropper and ran into an issue. How can I detect raw mouse events, such as mouse down, move, and up? I want to be able to detect these events even when outside the editor window. I am not using Unity’s old GUI system but instead a new UI system. In the OnGUI method when I check the current event the type is always either Repaint or Layout. It doesn’t fire mouse events.

private void OnGUI()
{
    var ve = rootVisualElement.Q<VisualElement>(null, "color-picker-window-container");
    if (ve != null)
    {
        ve.style.height = new StyleLength(position.height);
    }
    Event e = Event.current;
    if (sampleEyedropper)
    {
        if (e.rawType == EventType.Repaint)
        {
            colorPicker.SampleColor(e.mousePosition);
        }
    }
    if (e.rawType == EventType.MouseDown) //<-- Doesn't detect
    {
        Debug.Log("Down");
        sampleEyedropper = false;
    }
}

Figured it out. Apparently just using MouseManipulator did the trick.
