I've noticed libraries like rules_closure are able to trigger the live-reload server to activate, such that it serves the JS code to enable live-reloading at a local port (http://localhost:35729/livereload.js, for example), and so on. But how does one opt-in to this behavior?

I've affixed ibazel_live_reload and iblaze_notify_changes to my binary target, but to no avail. The endpoint still refuses connection for me. Am I missing a step?
