sequelize 獲取查詢結(jié)果(result)后， 如何在 result 上添加一個字段 ？

let result = await user.findOne({
    where: post
  })

const friends = await sequelize.query(
      `SElECT DISTINCT * FROM user WHERE id IN 
      (SELECT targetId FROM friends WHERE sourceId = "${result.id}")`
    )

// 下面這行代碼，未成功    
result.list = friends[0]
