Italy ECG on Fenix 7 Pro but do not start

I live in Italy, and as far as I know, the ECG app hasn't been activated in my country yet. However, to my surprise, the Garmin Connect app prompted me to activate the ECG app on my device. I have no idea how that's possible. The fact is that when I try to take the first measurement and place my index finger and thumb on the metal bezel, nothing happens. I've tried about ten times, but always with the same result.
