How to have FAB assets show up for download into UEFN?

Hello, I have a bunch of optimized free 3d assets on FAB I’d like to make available for the UEFN community, but cannot figure out how. On my listings the UEFN option is greyed out, sometimes not there at all. I followed FABs release closely with the hope to be able to publish for UEFN, but there has not been any public info released on how to do this. It seems like only a select few sellers are permitted, and it’s disappointing that this process has been private instead of including the community. Any update on when us indie developers will get a chance to get into the UEFN asset market?
