Mapster: how to instantiate an interface field with a specific implemetation?

Question

For example I have ObjectA:

public class ObjectA {
    public int ID { get; set; }
    public UserInfo UserInfo { get; set; }
}

and ObjectB:

public class ObjectB {
    public int ID { get; set; }
    public IDataUserInfo UserInfo { get; set; }
}

I want to map ObjectA to ObjectB. IDataUserInfo is an interface and there is an implementation for this interface called DataUserInfo. Both UserInfo from ObjectA and ObjectB have absolutely the same structure.

But after I call:

instanceOfObjectA.Adapt<ObjectB>();

I see that the actual type of the UserInfo field is GeneratedType_1. This is expected because our mapster doesn't know anything about our implementation of the IDataUserInfo interface.

How can I tell Mapster to use a specific implementation when materializing IDataUserInfo interface? I tried the following config but it still shows GeneratedType_1 instead of DataUserInfo:

public class MappingConfig : IRegister
{
    public void Register(TypeAdapterConfig config)
    {
        config.NewConfig<ObjectA, ObjectB>()
            .Map(dest => dest.UserInfo, src => new DataUserInfo { Field1 = src.UserInfo.Field1, ... });
    }
}
