View what has been edited in a ticket

In the “show activities” part of freshdesk you can see if someone has edited a ticket - but it doesn’t show what has been edited / the history of how it looked before the edit.
I am mainly thinking about e-mails coming in form clients for example. If someone decides to edit what the customer wrote it doesn’t show.

Or if someone creates a ticket and there is a conversations going back and forth there - they can edit everything and the only thing visible is that it has been edited. Not what has been edited.
