Oh, wow.. I wasn’t expecting that reply. I was actually looking to discuss in general how to address this variety of issue. It was a few years ago but the code would still be interesting to see. I dug this up:
https://dl.acm.org/doi/10.1145/2911988
And now that I dug back into this, I must make a correction. ACM replied to say they are looking for the missing material.. then they never found it and they dropped the ball at that point and also neglected correct the description. AFAIK, ACM did not try to reach the researchers, who ignored my inquiries.
(Irrelevant trivia: ACM used to be in Cloudflare’s access-restricted walled garden, making it difficult to access research. They are still in that shitty place but at least they are now whitelisting Tor which slightly reduces their exclusivity.)
Maybe the acknowledgments gives a hint?
(edit) there is also this about page and perhaps this lab was involved.
