Not sure that it's the same, but FWIW, I've used Pure Calendar Widget since I had the Note 3. It's highly customizable, though it looks like the app hasn't been updated in a few years. Haven't been able to pick up my Fold 3 yet, so I have yet to test the widget with a foldable.
I use the Pure Calendar widget, I really the customization options, but it is definitely very complex. Don't let the pictures on the Play Store fool you, you can make it look the way you like, as I have
It takes all the upcoming events on your calendar and compiles them onto a widget in list view. Fairly customizable, and it's a great way to make sure you don't miss any important dates/appts. Also has a quick entry option so that you don't have to go into your calendar app to add a new event.

I have been using that calendar widget for many years now, and I really recommend it with the transparent background.

One of the first apps on any new phone is Pure Calendar Widget (agenda version) because I literally can't live without it. It's a bit old at this point but I haven't found anything else that does what it does the same, and has the massive level of customization that it does. PLEASE don't judge it by its screenshots - there are tons of themes, you can change text size/scaling, etc. Mine is much smaller, condenses each calendar item onto one line, etc.
