Get page id of the logged event in UndoManager

[nguyenvoanhkhoa1]

Is there any way to get the page ID of the next undo/redo event? My case is when users call the undo/redo command, the editor will load the page to view the event.

Can you give me some advice @artf ? Is this possible? There is get Pages.Selected() in the before/after attributes of the stacks, but it gave me the current selected page, not the selected page in the past.
Thank you a lot.
