How to use the tangency continuity option of the NetSurf component?

Does anyone know how to utilize the tangency continuity option of the NetSurf Grasshopper component to emulate the way you can pick surface edges in the Rhino NetworkSrf command. I tried extracting edges using the Brep Edges component, but that seems to just output curve types with no surface tangency information such that it does not matter weather I input 1 or 2 into the continuity parameter of NetSurf. I have looked for an Edge primitive/type in GH but couldn’t find one. I found a post (link below) on this topic from several years ago which concluded that the NetSurf continuity input doesn’t really work - I hope that’s not the case. Thanks in advance for any help on this.
