Linking Car to OVO Charge App

On the OVO Charge App, should my car show just as a generic type, or should it be my specific car (i.e. VIN number/Registration number)?

On my OVO Charge App, under Account/Devices/Car there is a list of cars and models that presumably the OVO App supports and I have added my car model (Renault 5 E Tech 52kWh 150hp) and this (under “Vehicle Specs” in the OVO App) lists battery size and charging speed so that OVO knows what charge the connected car is capable of receiving; I assume.

It does leave me with the question of whether my specific car needs to link to the OVO App (and I don’t see a way yet of doing this) or whether this generic model link is the way to link the vehicle to OVO scheduling.

Sorry its a basic question!
