I can’t see anything specific in the link, and you probably already solved this… but just fyi, if it’s the same unit I used, and you are using arduino libraries, the library that worked was called one-bit display IIRC, and it basically acted as 1/4 of a ssd1306 64x128 oled, so you had to use x/y pixel offsets.
Yes, something like that that I found on Aliexpress: https://a.aliexpress.com/_EH7lHde
