How to add a "last modified by <user>"?

theme
#1

Hi, currently, we have multiple users defined for our system. I have added

Last Modified on <time datetime=" {{ page.date|date("M d Y") }}" class="entry-date entry-meta-element modified" title=" {{ page.date|date("M d Y") }}" itemprop="dateModified"> {{ page.date|date("M d Y") }} </time>

To our theme page.html.twig and it works well but I’d like to add also the name or email of the user who last modified that page. The page.header.author doesn’t help much as it’s not defined by default and I guess it wouldn’t necessarily be updated when an different user comes in and edit a specific page.

Any tips?
