Как добавить новый key value в JSON?

Решил сделать по-другому.

func findUser(UserID int) bool {
	file, err := ioutil.ReadFile("users.json")
	if err != nil {
		panic(err)
	}

	var user User

	err = json.Unmarshal(file, &user)

	for _, value := range user.Users {
		if value.ID == UserID {
			return true
		}
	}
	newUser := User{Users:  {ID: 1, Score: 0}}
	append(user.Users, newUser)

}

JSON:

{
  "users": [
    {
      "id": 1,
      "score": 123
    },
    {
      "id": 2,
      "score": 321
    }
  ]
}

Ошибки:

Missing expression
Unknown field 'ID' in struct literal
Missing expression
Cannot use '1' (type untyped int) as type struct {...}
Missing expression
Unknown field 'Score' in struct literal
Missing expression
Cannot use '0' (type untyped int) as type struct {...}
append(user.Users, newUser) evaluated but not used
Cannot use 'newUser' (type User) as type struct {...}

Как правильно распарсить JSON телеграма?

Евгений Самсонов,

{"ok":true,"result":[{"update_id":715296593,
"message":{"message_id":5,"from":{"id":362268798,"is_bot":false,"first_name":"\u041a\u043e\u0442\ud83d\udd25","username":".....","language_code":"ru"},"chat":{"id":362268798,"first_name":"\u041a\u043e\u0442\ud83d\udd25","username":"....","type":"private"},"date":1604728384,"text":"/start","entities":[{"offset":0,"length":6,"type":"bot_command"}]}}]}

uvelichitel, да ошибка срабатывает на этой строке

fmt.Println(data["result"].(map[string]interface{})["chat"])

Евгений Самсонов, нашел ошибку, два минуса у owner_id, а как теперь достать данные?

a[0], a.response
не помогают
