When adding links in navigation modules to pages within Refined, we recommend to use relative URLs.
This is especially important if you're using several instances (like test/staging and production) and reusing layouts between them.
Relative URL
Relative URL is the part of the URL that comes after the domain.
https://docs.refined.com/space/REFINEDCLOUD
Let’s say we want to add a navigation icon with a link to the above page on the main site of docs.refined.com . We can just add the part that comes after the domain, so /space/REFINEDCLOUD
