Programmatically connect translations

I recently switched to this plugin, converted my site to a multisite, and used the WordPress Site Cloner from Never Settle to clone my English site into German (DE) and Dutch (NL) subfolders. I now have three identical copies of the site.

The German and Dutch sites are currently set to ‘noindex’ and we plan to translate each page and post one by one. The language for these two sites is already set correctly, but the Multisite Language Switcher plugin doesn’t know which posts or pages are translations of the corresponding content on the original English site.

Now would be the perfect time to link the content, as the slugs for all posts and pages are still identical after the cloning process. This will change once we start translating them.

Is there a way to programmatically connect all the posts and pages on the German and Dutch sites to the corresponding content on the English site? For example, is it possible to loop through the English site’s posts and pages, find the equivalent content on the other sites using the slug as a key, and then use the other sites’ language settings to establish the connections?

Thank you!
