How to get started with the FT801 on Arduino?

I see that LVGL has example libraries for the Arduino IDE, and I also see that they have drivers on the FT80x (and I assume FT81x). But I am struggling to figure out how to get it to start working.

I have a shield for it where the example library uses FTDI’s example library, but I’d like to use LVGL (and eventually Squareline Studio).
