Availability of pre-trained CO and H2 models for BME688

In the BME AI-Studio Documentation FAQ, it is mentioned that:

"Regarding specific gases Bosch Sensortec has additionally tested the BME sensor to hydrogen sulfide (H2S), ethanol (EtOH) and carbon monoxide (CO) to which the sensor is selective to."

I understand that by default, the BME688 does not detect specific gases until trained by the BME AI-Studio software. However, from that quote above, it sounds like a pre-trained model or algorithm already exists for detecting CO and H2.

Are these available? If so, where can they be found?

Thanks in advance!
