ADUX1020 gesture question

I am currently working on the project which makes use of ADUX1020 board. The board is interfaced to the ADICUP3029. I am just making use of pins of J1 (SCL, SDA, 1.8V and gnd). I have attached the screenshot of the same. I doubt whether the LED is getting switched on since there is no significance difference in the data values of channels even when a gesture is performed. So, my question is do we have to use any other pins on the gesture board, may be (3.3 V pin) to get it working?
