func combineKeysAndValues(data map[string]string) string {
    var result []string

    for key, value := range data {
        // Format key and value as "key=value"
        result = append(result, fmt.Sprintf("%s=%s", key, value))
    }

    // Join all the formatted strings with ", "
    return strings.Join(result, ", ")
}

func main() {
    data := map[string]string{
        "Key1": "Value1",
        "Key2": "Value2",
        "Key3": "Value3",
