ADAU7002 and PDM Mic Connection Issue

Hello expert,

I have two simple questions on the ADAU7002 Eval Board. I have PDM microphone which has VDD, GND,CLK, DATA and L/R SELECT pins. It doesn't have power source.  (https://store.invensense.com/datasheets/invensense/UG-326.pdf
I check the UG-533 connecting the cables part, it said "because the board is being powered externally, leave the VDD jumper open"  Which jumper pin should I connect to the microphone VDD, L/R SELECT pin?
Meanwhile, I was using Arduino Zero to record I2S audio data. In UG-533m it said "connect SDATA,BCLK and LRCLK accordingly" Do I still connect the GND pin and VDD pin? If so, where should I connect the power pin?
Thank you very much and look forward for your feedback.
 Best,
