Fetch changed values in Add-ins

Summary

I want to fetch the changed Workspace values in Add-in

Content

Hi,

I am working on a Log which shows all the values that are changed by the user on any Workspace. Is there any way to get these values directly or i need to compare each and every value one by one.

Also, Is it possible to get all the Objects that are available on the workspace in Addin Record context object. For Eg: Contact is Parent of incident, Is it possible to get all the Contact fields via recordContext.

Thanks in advance
