hiptest-publisher push junit results

I have some existing test cases in CucumberStudio (on premise Hiptest branding) that are shells for recording an IT's success, while I have some corresponding Selenium/Junit ITs in CI.  I would like to publish the junit xml results against the corresponding ITs.  Is there a way to do this?  I can't find much information about how hiptest-publisher works, it's a black box to me.  So far my only success with it has been to download a feature file w/ uids, and publish the json results, but that's a different project.
