how do I add my name to comment boxes? I don't want it to be labelled as unknown author

I’m adding comment boxes to an essay i am marking. I want to add my name/initials to the comments boxes. I think the default is “unknown author”.

Thanks for any help

Tools → Options → LibreOffice → User Data → fill some fields. Now, because the document was created without those fields, you need to “assign it to yourself:” File → Properties → be sure “Apply user data” is selected and then press “Reset Properties.”
