How do I change the location of the GUILayout.BeginScrollView vertical scroll bar to be on the left hand side of the list rather then the right hand side?

I am using GUILayout.BeginScrollView() to manage a list that i have positioned on the left side of the screen. The vertical scroll bar cuts in the middle of the screen. I would like to have the scroll bar on the left hand side of the list, can anyone give me some ideas on how to do this?

you can change it by using
like this

private string longString = “”;
private Vector2 scrollPosition;
void OnGUI()

    GUI.BeginGroup(new Rect(Screen.width/2, Screen.height/2, 500, 500));

    scrollPosition = GUILayout.BeginScrollView(
        scrollPosition, GUILayout.Width(300), GUILayout.Height(100));
    if (GUILayout.Button("Clear"))
        longString = "";


    if (GUILayout.Button("Add More Text",GUILayout.Width(100), GUILayout.Height(50)))
        longString += "

Here is another line";
