Gorm after create, tx.Statement.SQL.String() got empty

I tried this, but not got the expectation.

func (cars *CARS) AfterCreate(tx *gorm.DB) (err error) {
    fmt.Println("hook after =>", tx.Statement.SQL.String())
    return
}

/*
Insert ...
*/
func (cars *CARS) Insert(ctx context.Context) error {
    tx := db.Create(cars)
    fmt.Println("did ===>", tx.Statement.SQL.String())
    return tx.Error
}

output

hook after => INSERT INTO `cars` (`name`) VALUES (?)
did ===>

get the SQL before execution (use plugin) or look this doc https://pkg.go.dev/gorm.io/gorm#DB.ToSQL
