In the latest Logseq Times daily notes page set up. What plugin is the person using?

I just read logseq times and they had someone’s daily notes page set up, and I was wondering how that person got the daily notes page to look like that. It looks like a plugin, but when I look in the marketplace, I don’t see any plugin that does that. I believe his name was Alex but here is the screenshot https://www.logseqtimes.com/content/images/size/w2000/2023/07/image-14-1.png
