ADXL343 Watermark interrupt

Hi,

I have an Adafruit adxl343 accelerometer breakout board: link

I am connecting it to an ESP32 and programming it using the arduibo IDE. I would like to make use of the watermark interrupt and the FIFO queue but I cannot find any examples of how to do this. I am using the Adafruit libraries that the tutorial suggests.

I am ingratiating this into a larger GPS lap timer and data logging project, I could read the data every time a sample is ready but I feel it would be more efficient for the ADXL343 to collect data into it's own queue and then for the ESP32 to read it when a certain number of samples is reached.

Does anyone have an example or recommended alternative library that I could use?
