How to read the current PivotRotation or PivotMode ?

There's a undocumented class in UnityEditor namespace called Tools. It has a static property pivotRotation, that returns a PivotRotation enum (Local or Global) and another one called pivotMode, that returns a PivotMode enum (Center or Pivot).

 public class Tools : ScriptableObject
 {
     //(...)
     
     public static ViewTool viewTool { get; set; }
     public static PivotMode pivotMode { get; set; }
     public static PivotRotation pivotRotation { get; set; }
 
     public static Vector3 handlePosition { get; }
     public static Quaternion handleRotation { get; set; }
     public static Quaternion handleLocalRotation { get; }
     
     //(...)
     
 }
