Bosch BSEC Libary Humidity Calibration

Hello, did someone use the BSEC Library to calibrate Humidity?
the library has a settempoffset parameter but im unsure on how to calibrate humidity

Maybe there is a way through the SensorAPI? could someone help me with that?

Library is GitHub - BoschSensortec/BSEC-Arduino-library: Arduino library for BSEC to simplify integration into compatible platforms. To report issues, go to https://community.bosch-sensortec.com/t5/Bosch-Sensortec-Community/ct-p/bst_community
