As detailed in the tutorial: https://learn.adafruit.com/adafruit-ein ... ld-pinouts you will need to connect the 3 SPI bus connections as well as 4 digital outputs for the various select/control signals.

SCK, MISO, and MOSI just get connected directly between the feather and the shield.
D10, D9, D8, D5 on the shield need to connect to 4 GPIO lines on the feather. The ESP32 feather doesn't have pins labeled D10, D9, D8, D5 so you'll need to select 4 that are not being used and adjust the code accordingly to pass those pins to the Adafruit_IL0373 constructor.
