Struct InnerUndoManager 

pub struct InnerUndoManager { /* private fields */ }

UndoManager is responsible for managing undo/redo from the current peer’s perspective.

Undo/local is local: it cannot be used to undone the changes made by other peers. If you want to undo changes made by other peers, you may need to use the time travel feature.

PeerID cannot be changed during the lifetime of the UndoManager
