How to get the coordinate of next junction in Veins 5.2

Question

I'm new to Omnetpp and Veins. I'm triyng to write an application modifyng the existing TraciDemo11p application in Veins. Now I'm stuck since I don't know how to get the coordinate of the next junction for the vehicle. I saw this: how to calculate distance between car and next junction in veins

since it is what I need, but it is really old (Veins 3) and I saw the interface are changed.

I tried to serch online without good results. I also saw that in the TraciCommandInterface there is this part of code:

// Junction methods
    std::list<std::string> getJunctionIds();
    class VEINS_API Junction {
    public:
        Junction(TraCICommandInterface* traci, std::string junctionId)
            : traci(traci)
            , junctionId(junctionId)
        {
            connection = &traci->connection;
        }

        Coord getPosition();
        std::list<Coord> getShape();

    protected:
        TraCICommandInterface* traci;
        TraCIConnection* connection;
        std::string junctionId;
    };
    Junction junction(std::string junctionId)
    {
        return Junction(this, junctionId);
    }

I think that what I need is to call the getPosition() method, but I don't know how since I think I have to refer to the next junction object. How to do this? Thank you.

Thanks
