For those "smart features" is says "with compatible smart watch".
I would guess the processing from Accelerator data to semantic features is done in watch, not chest.
The H10 also has a accelerometer. I know from own experience that this is easy to get (did it with python program on PC, but should be pretty easy from bangle as well).
Now the question is if and how the analysis can be done for the features you want.
Stride time might be pretty simple, which could give stride length together with smoothed gps from bangle or phone, etc.
