請問我該如何做mapper才能把Assets的資料利用關聯性includes進來呢?

MapperConfiguration = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<UserBalancesDto, UserBalances>();
}

public class UserBalancesDto
{
    public Int64 id { get; set; }
    
    public Int64 asset_id { get; set; }
    
    public virtual Assets assets { get; set; }
    
    public string user_id { get; set; }

    public decimal total { get; set; }
}

public class Asset
{
    public Int64 id { get; set; }
    public string name { get; set; }
    public decimal amount { get; set; }
}

public class UserBalances
{
    public Int64 id { get; set; }
    
    public Int64 asset_id { get; set; }
    [ForeignKey("asset_id")]
    public virtual Assets assets { get; set; }
    
    public string user_id { get; set; }

    public decimal total { get; set; }
}
