Sharing newest posts to a second web site?

Hello there.

A client has one old site. Along with a newer site.
The old site remains as a kind of archive. While the new site has a lot of new material.

The use case.
Site one.
This page: https://religionskritikk.no/nettmagasinet/nettmagasin-edwien/ Has articles about Edwien (One specific category).
They would like the two newest articles to be shared to the second site edwien.no.

Is it possible to select a category and for instance 2 posts to automatically be shared from one site to another? If that is not possible with this plugin do you have any thoughts as to how I might do so without hand coding this feature?

Thank you! Have a great day!
