How to upload TCX file from Polar Flow to Garmin Connect

Introduction I used a Garmin 310XT since 2015 and it works very well until now. However I would like to measure some data from my sleep time. Thus I was wondering to buy a new watch. My first idea was a Garmin, but the prices in Brazil were a little bit bitter that moment. I made a research and found out some Polar models, and after all I bought a Polar M2.
