        : base(path, scope)
    {
    }

    [SettingsProviderGroup]
    public static SettingsProvider[] CreateProviders()
    {
        var files = Directory.GetFileSystemEntries(k_XRSettingsFolder, "*.json");
        return files.Select(entry =>
        {
            // First parameter is the path of the settings in the Settings window.
            return new XRSettings("Project/XRSettings/" + Path.GetFileNameWithoutExtension(entry));
        }).ToArray();
    }
