Zhiyun Crane 2 and "hack" for Sony cameras


A few years ago there was a "hack" that allowed you to control a Sony camera from a Zhiyun Crane 2, even features like shutter and aperture that weren't officially supported, by using a Canon cable and putting the Sony camera in USB "PC Remote" mode. A few of the videos about the subject are:

To my regret, I didn't find out about that hack in its time, and now that I've discovered, I have been trying it with my Sony A7IV camera... and of course, it doesn't work.

Does anybody know if there's a way to make it work as of today? My Crane 2 has the v1.73 firmware, while the last version released was the 1.77. Maybe I should upgrade, but OTOH, one of these videos mentions that he is using v1.72 to make it work.
