Right Clicking Program in Tray

Hi there, a new user of AutoIt so please bear with me!!

Simply I'd like to right click a program in the tray area, in this case the program is Google Drive. Now sometimes the tray icon is in the main bit, but sometimes you have to click the little arrow and it's in that area. Sorry for the bad explanation, I can't think of the correct technical terms!!

I used the simple mousemove command at first but then realised when testing that the icon moves around on different computers.

So any help on how I could go about this would be much appreciated.

Thanks,

Tom
