Question "PredictionRigidbody" struct FishNet

I'm working with the current version of FishNet. I'm trying to use Prediction v2 but I don't have the PredictionRigidbody struct. Unity tells me that no such struct exists

Code (CSharp):

1. public struct ReconcileData : IReconcileData
2. {
3.  
4.     public RigidbodyState RigidbodyState;
5.     public PredictionRigidbody PredictionRigidbody;
6.  
7.     public ReconcileData(PredictionRigidbody pr)
8.     {
9.         RigidbodyState = new RigidbodyState(pr.Rigidbody);
10.         PredictionRigidbody = pr;
11.         _tick = 0;
12.     }
13.  
14.     private uint _tick;
15.     public void Dispose() { }
16.     public uint GetTick() => _tick;
17.     public void SetTick(uint value) => _tick = value;
18. }
