Blender Secrets - The Sketchfab add-on

The Sketchfab website now has an add-on for Blender that makes it possible to search for and import models into Blender from inside the Blender interface. This is the link that worked in Blender 2.83 for me. The official page points to a different version (however that one didn't work for me).
