How to get EditorWindow client rect?

I want to create a simple console-like custom EditorWindow in Unity. There is a bunch of lables (console lines).

I'm using GUILayout.Begi/EndScrollView to position all the labels in one column. The problem is that it places all the content inside the rectangle that matches label bounds, not EditowWindow bounds. As a result, I see weird placed scrollbars.

I would be happy to recalculate ScrollView bounds, but can't find any clue in documentation how to make so. Here is my code:

 using UnityEditor;
 using UnityEngine;
 using System;
  
 public class MyEditorWindow : EditorWindow
 {
    Vector2 scrollPosition = Vector2.zero;
  
    [MenuItem("Window/MyEditorWindow")]
    public static void ShowExample()
    {
        var wnd = GetWindow<MyEditorWindow>();
        wnd.titleContent = new GUIContent("MyEditorWindow");
    }
  
    private void OnGUI()
    {
        scrollPosition = GUILayout.BeginScrollView(scrollPosition, GUILayout.Width(position.width), GUILayout.Height(position.height));
  
        var elapsed = new TimeSpan();
        for (int i = 0; i < 100; i++)
        {
            elapsed = elapsed.Add(TimeSpan.FromSeconds(1));
        }
  
        for (int i = 0; i < 100; i++)
        {
            GUILayout.Label("Some long long long long text");
        }
  
        GUI.EndScrollView();
    }
 }

What is the proper way of making scrolbars which bound to the edges of the EditorWindow?
