help with SEN-CCS811 CO2 sensor

Hey guys, I have searched on the forum but have not found an answer to my problem.
I am transferring a project over to a rev2 board from an UNO and everything is working but the sen-ccs811 Co2 sensor.
I have tried several libraries and they dont seem to work on the rev2 board.
Can anyone tell me what I would need to change or add to make it work on the rev2?
what would the differences in the code be from this board(REV2WIFI) to an older UNO?
Sorry if this is a silly question but I am new and still learning!

thanks in advance for any help

also to help me you will need more info from me but I am not sure what is needed. so please tell me what and I will post.
