Notes:
- You can build a system to automatically duplicate template page or last page. GoogleSlidesDuplicate
- For example, if you want to automate the notification of "Monthly Sales Report", define as follows:
    - The template page is automatically duplicated (Google Slides: Page, Duplicate)
    - The report text part is automatically replaced (Google Slides: Page, Replace Strings)
    - The embedded graph is automatically updated (Google Slides: Page, Refresh Charts)
    - The slide page is automatically converted to a PNG image (Google Slides: Page, Generate PNG)
    - The email with the PNG image attached will be sent automatically. (ThrowEmail Event)
Notes-ja:
- Googleスライド内の雛形ページや末尾ページが自動複製される仕組みを構築できます。GoogleSlidesDuplicate
- たとえば「月次売上レポート」の通知業務を自動化したい場合は、以下のような業務プロセスを定義します。
    - 雛形ページが自動複製され、（※Google スライド: ページ, 複製）
    - 貼り付けられている埋め込みグラフが自動更新され、（※Google スライド: ページ, 文字列全置換）
    - 報告テキスト部が当月文に自動置換され、（※Google スライド: ページ, 全グラフ更新）
    - 当該スライドページがPNG画像に自動変換され、（※Google スライド: ページ, PNG画像生成）
    - PNG画像が添付されたメールが自動的に送信される。（※ ThrowEmail イベント）
