Clojurians Log v2

Hi, I'm trying to run some tests in chrome, with similar setup as described here https://figwheel.org/docs/testing.html, so using :launch-js, but I'd like to run the whole thing from a clojure function, rather than a command line. I have been trying to use figwheel.main.api/start, but probably missing some options as it compiles but then keeps the fig process running, and does not do the launch. does anyone have some sample config to do this?
