The link at the end is both shortened (for tracking purposes?) and unclickable… so that’s unfortunate. Here is the real link to the paper, in a clickable format: https://dl.acm.org/doi/pdf/10.1145/3385412.3386037
Thanks for pointing that out. It should be fixed now. The shortening was done by the editor I was using ("Buffer") to draft the tweets in - I wasn't intending to track one but it probably does provide some means of seeing how many people clicked the link
