Ublox NINA module datasheet does not have SPI instructions

I'm trying to comb through the data sheet of the ublox wifi module listed on the wifi mkr 1010 page and it links to the NINAW102 data sheet that does not seem to have any SPI commands listed for you to interact with the chip. However, when I go combing through the library the SPI commands that interact with the NINAW102 are listed under "wifi_spi.h".

Where do these commands come from if not listed online?

the NINA module is a MCU (esp32) with Arduino nina firmware
