Just FYI, to me, separating and doing "Cleare All" first then "Close" works better.

tell application "System Events"
  try
    repeat
      set _groups to groups of UI element 1 of scroll area 1 of group 1 of window "Notification Center" of application process "NotificationCenter"
      set numGroups to number of _groups
      if numGroups = 0 then
        exit repeat
      end if
      repeat with _group in _groups
        set _actions to actions of _group
        set actionPerformed to false
        repeat with _action in _actions
          if description of _action is in {"Clear All"} then
            perform _action
            set actionPerformed to true
            exit repeat
          end if
        end repeat
        repeat with _action in _actions
          if description of _action is in {"Close"} then
            perform _action
            set actionPerformed to true
            exit repeat
          end if
        end repeat
        if actionPerformed then
          exit repeat
        end if
      end repeat
    end repeat
  end try
end tell

I'm getting the following error on macOS Sonoma 14.3.
