getting oxygen saturarion data from garmin watch

I have a vivoactive 4 model garmin watch and this watch has a sensor to measure oxygen saturation. I want to capture oxygen saturation data from this watch, but although I can measure oxygen saturation from the watch, the data does not appear when I connect the watch to the computer. Likewise, I downloaded Garmin Connect to my phone and when I want to view the data from there, The data appears to be measured there, but the data still cannot be received.
