// (config "Redirect URL" = "https://s.questetra.net/oauth2callback" )
// (Scope: "read" or "any" )
// Set ID&Secret: Workflow App > Detail > OAuth2 Setting > (Get Refresh Token)

// Notes:
// Tab code and line feed code in Workflow data will be deleted.
// Workflowデータ内のタブコードと改行コードは抽出時に削除されます
// Specify "Title" to extract Title and "Id" to extract ID. ( e.g. "Title,Id,0,2,3" )
// 案件タイトルの抽出には "Title" を、IDの抽出には "Id" を指定します ( 例 "Title,Id,0,2,3" )
// If an undefined dataitem ID or Guide Panel ID is specified, "#N/A" is output.
// 未定義のデータ項目IDやガイドパネルのIDが指定された場合は、"#N/A" が出力されます
// If an unsupported type is specified, "#TYPE!" is output.
// サポート外のデータ型が指定された場合は、"#TYPE!" が出力されます
// The file names are extracted for the File type. (Multiple: Space-separated)
// ファイル型を指定した場合、ファイル名が抽出されます（複数：スペース区切り）
// The display strings of the selected options are extracted for the Select type. (Multiple: Space-separated)
// 選択型を指定した場合、表示テキストが抽出されます（複数：スペース区切り）
// It supports loop processing.
// ループ処理に対応しています（抽出結果の追記）
