FreeStyle Libre, Libre 2 and Libre Pro Sensor Reading on Apple Watch without the iPhone

On several public forms, from Apple watch users in the UK, Canada and Germany I heard they can see glucose readings from FreeStyle Libre, Libre 2 and Libre Pro sensors on their Apple watch without he iPhone and if watch is series 3 and higher then they can also share readings with the caregivers using Ambrosia's blucon device and LinkBluCon app, is it true? I looked at Ambrosia website https://www.AmbrosiaSys.com seems it is available in most countries
