So, i did all that and downloaded the tool and run that command and found out that the feature is "experimental" and not included in the binaries. It's a bit strange: the tool got my attention, and i was ready to experiment, but i couldn't.
If the reason is that it's a paid or saas only feature, that's totally fine but i think authors should make it a bit more obvious from the web page. Otherwise, i'd suggest to put "experimental" binaries there, too.
