Fermer certaines notifications à l'aide d'AppleScript

Il s'agit du script :

tell application "System Events"
    tell process "NotificationCenter"
        set numwins to (count windows)
        repeat with i from numwins to 1 by -1
            tell window i
                set temp to value of static text 1
            end tell
            if temp contains "Disk Not Ejected Properly" then
                click button "Close" of window i
            end if
        end repeat
    end tell
end tell

Et voici l'erreur que j'obtiens :

error "System Events got an error: Can’t get static text 1 of window 1 of process \"NotificationCenter\". Invalid index." number -1719 from static text 1 of window 1 of process "NotificationCenter"
