Steps with timestamp?

I've used SDK to convert fit files to csv, but I seem to be missing where my daily steps are recorded?  I'm looking for something like this:

Sep 6 2024 1:01 PM: 50 steps

Sep 6 2024 1:02 PM: 90 steps

Sep 6 2024 1:03 PM: 92 steps

I understand the timestamps will likely be in Epoch dates, and am prepared to convert those, but just haven't been able to find where the steps by minute are actually recorded? 

The main reason I want to do this is to avoid double-counting steps. For example, elliptical might be recorded as a workout but steps also accrue during that time period, and I'd like to be able to back out from the data the duplicate recording of activity. FitBit provides the step count by minute which allows for duplication to be removed but I'd like a way to do this using only Garmin data.

Can anyone help?  Thanks in advance for any help!
