Calculate co2 and h2s with Bme688

Hello we want to know how we can get the co2 and h2s value in ppm by Bme688 sensor,this is very important for us that true answers for our questions.

1- can we use default bsec algorithms or we need bosch shuttle Bme688 development kit?

2- if we need shuttle how can we use import algorithm in bsec library?( After make algorithm step by ai studio )

3- can 1 sensor enough to detect co2 and h2s after training by shuttle Such as your tests with coffee (normal air coffee1 normal air coffee2) , or we need 2 sensors one of them for co2 and other for h2s to calculate with high reference?

4- is there any sample codes for detect and print co2 and h2s with esp32 ardunio ide c++?
And any other information that you can give us to help our project to do.

Best Regards
