Update on this, I investigated, through a series of security fixes we increased the constraints around artifacts.
For an artifact to show up now it needs to be marked public and the actual post that “created” it also needs to be in a public share.
This is way too strict and limiting, I am seeing if I can add a new system to just share a single artifact alone (and see a list of your artifacts) this is a very important system, but very hard to use now.
