Applescript 如何在任务控制中设置复选框？

我正在尝试在“系统首选项”的“任务控制”窗格中设置复选框。到目前为止，我能够打开MC，但我不知道如何点击复选框。我在网上找到的所有东西都试过了，但没有成功。。。 我怎么做

告诉应用程序“系统首选项”激活将当前窗格设置为 窗格“com.apple.preference.expose”结束

仅当当前未选中窗格的第一个复选框时，才会单击该复选框：

tell application "System Preferences"
    set current pane to pane "com.apple.preference.expose"
    activate
end tell
tell application "System Events"
    tell process "System Preferences"
        set firstCheckbox to checkbox 1 of group 2 of window 1
        set checked to value of firstCheckbox as boolean
        if (not checked) then
            click firstCheckbox
        end if
    end tell
end tell
