Hi Sercin,

You can do this by searching in the tree view. Most of the views that have an archiving function
have a filter "Archived" which you can apply by default. If it doesn't exist in the search
you can create a custom filter "Active is false":

Afterwards you can select the records you want to unarchive in the tree view and click
on Action > Unarchive. Alternatively you can open up the archived record and unarchive
it by clicking on the smart button.

Regards,
Yenthe
