How to fetch the timestamp of the states of an lifecycle managed object?

Hi All,

Happy new year to all.

I am trying to fetch the timestamp of the lifecycle state when it gets changed.

For eg: I have an WC object type "Complaint Prodcut Investigation" It has lifecycle states "Request", "Return Product processing, "Product Investigation", "Closed" & "Canceled".

I am trying to fetch the timestamp of these lifecycle states in the process. Any lead in customizating this is very helpful

Thanks & Regards
