Clojurians Log v2

how should the preloads work? this doesn’t seem to work:

#kaocha/v1
{:tests [{:id   :unit
          :type :kaocha.type/clojure.test}
         {:id   :unit-cljs
          :plugins [:preloads]
          :kaocha.plugin.preloads/ns-names [sci.core]
          :type :kaocha.type/cljs}]}

tried also adding those to top-level, with no luck.
