How do I add links to my project documentation in Webflow University?

I have seen some links to 3rd party sites, like Integrations | Plugins and integrations library | Webflow University

How do I add my link there so others can access my tutorial?

In the designer “share project”, then click on the switch.

I meant how do I generate an entry in Webflow university like this?

This links to enrollsy, I wanna link to my documents.
