I'm trying to install cljs-devtools using deps.edn and figwheel-main. cljs-devtools says that I should put :external-config {:devtools/config {:features-to-install [:formatters :hints]}}} in the compiler options if using lein or boot. I tried putting it in my dev.cljs.edn file but it didn't seem to work. Should it? :external-config is not documented in figwheel-main.

Apparently it should work, but when I check with (devtools.core/installed? :hints) it returns false.
