SPARKFUN BATTERY BABYSITTER - LIPO BATTERY MANAGER ARDUINO LIBRAY

Hello,
I have purchased the SparkFun Battery Babysitter - LiPo Battery Manager and started using the library provided for Arduino GitHub - sparkfun/SparkFun_BQ27441_Arduino_Library: Arduino library for the BQ27441 LiPo Fuel Gauge.

On that Arduino Library, how can I read 2 bytes from extended data specifying a class ID (Subclass ID-89) and position offset (0 to 28)? I am basically trying to read the Ra table values on page 32 at the reference files attached.

Thanks for your time.
