Can we create an object using a string holding class name in C++? [duplicate]

In the below example, I extract the class name from the template type T. Now I want to use this string to create an instance of a class. Is there a way to achieve it in C++?

template <typename T>
class factory
{
    T obj;
    std::string class_name;
public:
    factory(T obj)
    {
        this->obj = obj;

        class_name = boost::typeindex::type_id<T>().pretty_name();
        
        //some magic here
        class_name instance;
    }
};
