NEED HELP: Creating Custom Game User Settings (CPP)

So… how I can create this custom INI?

With this?

// INITIALIZER CONSTRUCTOR (DEFAULT)
UCndSysSave_UserSettings::UCndSysSave_UserSettings()
{

GGameUserSettingsIni = FPaths::ProjectSavedDir() + TEXT("CndGameUserSettings.ini");

CreateCustomIniFile():

}
void CreateCustomIniFile()
{

	// if (FileExists) {} else {}

	FString CustomFileName = FPaths::ProjectConfigDir() + TEXT("CndGameUserSettings.ini");
	FString SectionName = TEXT("CustomSettings");
	FString KeyName = TEXT("Version");
	int32 Cnd_Version_Initial = 1;

GConfig->SetInt(*SectionName, *KeyName, Cnd_Version_Initial, *CustomFileName);

GConfig->Flush(false, *CustomFileName);

}
