Arduino library/code for PIM448 (ICM20948)

Hi,
I want to use the PIM448 breakout board to test the ICM20948 chip (before putting it into my custom PCB). Is there an Arduino library or example firmware code to use with this PIM448 board? I could only find an Adafruit library for their board with ICM20948 (Adafruit ICM20X), but it couldn’t detect the ICM20948 when I connected the PIM448 with Arduino. What should I connect the INT pin to if I just want to read the data continuously (I guess it’s an interrupt pin)?
Additionally, where can I find the schematic of the PIM448 board?
Thanks,
Han
