Yes, you can set the autoposting when the post is published or updated or when scheduled in WordPress.
That is all under site settings on the platform.
Just log in and click on the “Websites” in the menu sidebar which will open your website url. Click on that and you will go to that website settings page.
On the first tab, you just tick the “Share on update”, click save and that is it.
Also, keep in mind regarding the Exclude/Include categories tab (3rd tab on the website settings page). If you have some categories as included there only the posts that got updated from those categories will be shared. If you don’t have any categories in the included, just under excluded, all posts that got updated will be shared – except posts that are in the excluded categories.
