While in-game, trying to send a click to a popup notification outside of game without losing active focus

[Nacho21]

Hello, I am trying to make a script. While playing a game l want to send a click to a popup notification (outside the game) without interfering with the game at all. I am pretty sure I need to use ControlClick however since it's not really a different window just like a popup/notification I having a hard time getting it to work. I used the window spy and tried all the available names/positions/classes but I think I am doing something wrong. This is an image of the windows spy of what I want to click http://i.imgur.com/Kafn9ys.png . Any help would be appreciated.
