Can someone from the Garmin team share how the csv file should be formated for it work? 

I am not from Garmin, but the following file works for me fine:

Body
Date,Weight,BMI,Fat
"2022-11-03","71.6","22.6","14.4"

There can be multiple lines of data, but the first 2 header lines appear just once. Use a plain-text editor such as Notepad for creating the file. Do not use any rich-text editors like Word or Wordpad. And avoid Excel !
