Serial Monitoring ESP32 with BME688 Dev-Kit

Hi everybody,

I am completely new in that area and facing an issue with my BME688-DevKit.
So I would like to monitor the Outputs of the ESP32. Therefore I try to get to run on of those example from this libary: Bosch-BSEC2-Library/examples at master · boschsensortec/Bosch-BSEC2-Library · GitHub

But honestly I do not even know which file I have to upload. I have tried some .ino and some .cpp files. It seems like I can upload both on the board (Takes 50 min :o) but the serial Monitor is always empty.

I hope I just forgot to do something beforehands.

Thank you!
