OLED and I2C converter

I’m using the “USB to I2C Converter with Virtual COM Port FT230XS” to connect to an OLED display.

Does the converter transmit the NCD API packet or just the I2C data over the wire?

Is the “OLED 128x64 Graphic Display I2C Mini Module” required to receive NCD API packets to communicate via I2C with the OLED display?
