在 Applescript 中显示桌面 - 需要帮助

Question

我需要以下方面的帮助。我想创建一个脚本来复制 Windows 的“显示桌面”。但是它不起作用，有人能帮忙吗？

然后我想将其保存在我的 Dock 中，这样我就可以根据需要单击它来显示/隐藏桌面。谢谢。

property windows_hidden: "not set yet"
    if windows_hidden is false then
        activate application "Finder"
        tell application "System Events"
            set visible of processes where name is not "Finder" to false
        end tell
        tell application "Finder" to set collapsed of windows to true
        set windows_hidden to true
    else
        activate application "Finder"
        tell application "System Events"
            set visible of processes where name is not "Finder" to true
        end tell
        tell application "Finder" to set collapsed of windows to false
        set windows_hidden to false
    end if
