Событие PowerChell для всплывающих уведомлений onClick для отображения сообщения из базы данных.

Question

У меня есть событие onclick для всплывающей подсказки, генерируемой сценарием. после нажатия он помечает конкретную запись в таблице mssql как прочитанную и ссылается на URL-адрес веб-приложения, отображающего сообщение. Как лучше всего показать это сообщение в окне сообщения или окне Windows CMD?

        $notification.BalloonTipText = "Click here to view"
        $notification.Visible = $True
