adjust trigger for VL53L8CX

Hi,

I have a VL53L8CX Sensor on a Satel-VL53L8 board that I am controlling with a custom microcontrollerboard that has an ESP32-S2 chip. I want the microcontroller to sleep until the sensor triggers the Int Pin, based on a threshold that I configure in advance. My knowledge of configuring thresholds goes as far as the provided example of the VL53L8CX arduino library (here). I havent really found a documentation for configuring interrupts.

As far as I understand the Int Pin trigger has to be a falling edge. However I think the sleep method of the ESP does not provide a falling edge trigger for waking up (see). Only triggers on low/high level are allowed.

Therefor my question is, if it is possible, to adjust what kind of trigger the Int Pin sends? And where can I find more documentation about thresholds and interrupts of the VL53L8CX? (Sorry, if I overlooked it)
