Tuning APDS 9960 gesture sensor

Hello,

i recently bought such a sensor device and think its really neat, but i have trouble using it behind a windowglass. What can i do to get i recognizing the gestures in such a setup?
Are there any tuningparameters, special mounting hints or such?

Thanks a lot for any hint!

I did, multiple times, but i does not bring me further. Only thing was, to use a part onside the optiks to prevent crosstalk between sender LED and sensors.

The datasheet tell that the glass should not exceed a thickness of 1mm. Do you know what is bad then? And what about double glass windows? Can i measure the IR "throughput" of my windows to know if there are filtern preventing it from working?
