Links format
This plugin stores the internal links in a specific format. That format looks something like this:
wt-link://api::page.page/sp8bzbkn21pjy3m9wsf97dio?locale=en
This makes it possible to fetch the page, and ultimately the URL alias of the document that you have linked to.
The plugin provides a rewrite middleware so that this link format will be rewritten to the actual URL at request time.
