How to debug the `figwheel-sidecar` project?

Question

How can the figwheel-sidecar project be running on my own machine with my Emacs so I can debug into it?

I tried to cider-jack-in, it works, but how to let the clojurescript project depends on it and let Emacs run the local version of figwheel-sidecar?

Key steps

;; ~/.emacs.el or ~/.emacs.d/init.el

(require 'cider)
(setq cider-cljs-lein-repl
      "(do (require 'figwheel-sidecar.repl-api)
           (figwheel-sidecar.repl-api/start-figwheel!)
           (figwheel-sidecar.repl-api/cljs-repl))")
