At the moment, it doesn't work yet. Polar is constantly releasing new software updates, I think this will come. You can find the information in the product comparison on the Polar website (https://www.polar.com/ch-de...) under "Smart Notifications".
With the firmware update 3.0 from 11.02.2019, the "Smart Notifications" function was added. Smartphone messages can now be displayed on the Vantage V and M.
