如何使用其他结构变量访问不同的结构变量?

I have two structs and one containing one field and other contains three fields:-

type User struct {
  Name []CustomerDetails `json:"name" bson:"name"`
}
type CustomerDetails struct {
  Value             string `json:"value" bson:"value"`
  Note              string `json:"note" bson:"note"`
  SendNotifications bool   `json:"send_notifications" bson:"send_notifications"`
}

I want to access the CustomerDetails fields using the User struct field like

func main() {
  var custName User
  custName.Name.Value = "ABC"
  fmt.Println(custName)
}

But It gives me the error of

custName.Name.Value undefined (type []CustomerDetails has no field or method Value)

Playground link

How will I solve this error? Can anyone help me?

    type User struct {
      Name []CustomerDetails `json:"name" bson:"name"`
    }
    

    Here, User.Name is slice, that's why you are getting error.

    func main() {
      var custName User
      custName.Name = append(custName.Name, CustomerDetails{
        Value: "ABC",
      })
      fmt.Println(custName)
    }
