How can I set EditorWindow to be in the center of the screen?

using UnityEngine.SceneManagement;

public class Prefab : EditorWindow
{
    [SerializeField] private GameObject prefab;
    List<Transform> transformSelection = new List<Transform>();
    int transformsCount = 0;

    [MenuItem("Tools/Prefab")]
    static void CreatePrefab()
    {
        EditorWindow.GetWindow<Prefab>();
        //GetWindow<Prefab>().position = new Rect(980, 380, 322, 278);
        GetWindow<Prefab>().position = new Rect(Screen.width / 2, Screen.height / 2, 322, 278);
    }

This put the window in the center by width but on the top of the screen.

I'm not sure that even the width is in the middle. But the height is on the top.

The big white rectangle is the window.

Working solution:

    int width = 322;
    int height = 278;
    int x = (Screen.currentResolution.width - width) / 2;
    int y = (Screen.currentResolution.height - height) / 2;

    GetWindow<Prefab>().position = new Rect(x, y, width, height);
