Close certain notifications using AppleScript

This is the 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

And this is the error I'm getting:

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"

I'm running MacOS Big Sur 11.4

Solution 1:

Can’t get static text 1 of window 1

The Notification Center window does not contain a static text as an immediate child. You need to navigate the hierarchy down to the texts within a notification.

get static text 1 of group 1 of UI element 1 of scroll area 1 of window i

Can’t get button "Close"

You also can't click a button that doesn't exist. Perform the close action on the notifications instead, which you can get using actions … where description is "Close".

perform (first action of group 1 of UI element 1 of scroll area 1 of window i where description is "Close")
