Health Connect Question for those that have upgraded to Google Health app.

I am pretty interested in the new Fitbit air but have a few questions, more around the new Google Health app + FitBit watches for those that have used it in public preview for a while now.

Does the new app write SpO2, Skin Temp, Respiratory Rate and HRV to android's health connect? If so at what interval? 1min intervals? or only averages? This is specifically for sleep.

I have a custom app I use to analyze and visualize my health data, I am currently using a galaxy watch, and while Samsung Health does not write this data to Health Connect, the galaxy watch runs WearOS so I could write my own software on top of it to access the sensors and get the data, but with the FitBit air I doubt there will be any hardware level SDK, at least not in the early stages.
