ECG with Polar H10

Hi, I currently trying to receive ECG from Polar H10 using a BLE connection.

I try to discover the services and their UUID but I couldn't find the ECG service.

I'm using nRF Connect to discover the services.

Does anyone know which one is the ECG service?

I can't answer this question, but from having written code to interface to the H10 before, I can say that Polar has very good documentation on their site!
