Marking up a page that references a CreativeWork elsewhere on the web

Hi all,

This is the first time I have had to address this particular case and I am
stumped.

I am writing the Schema markup for a "press articles" section in a website,
where basically each page contains a screenshot, headline and link to the
original article which is in a different online publication on a whole
other website.

How do I write the Schema so that the mainEntityOfPage in a page on
https://www.tots.fr/ correctly references an article published, for
example, on https://maison.20minutes.fr/? Do I use the "Citation" type?

I basically want to do something like this :
========================================

"@type": "WebPage",
(...)
"mainEntityOfPage": {
  "Citation" (????)
    "@type": "Article",
    "headline":"Les plus beaux modèles de vasques pour la salle de bain",
    "inLanguage":"fr-FR",
    (...)
    "url":"https://maison.20minutes.fr/mm43354-modeles-vasques-salle-de-bain/"
  }
},

=======================================

Or do I just define it as an article and it's clear from the URL that it is
hosted on another site?

I've searched everywhere for this and haven't found anything yet. Can
anyone point me in the right direction?

Thanks!
