Another thing that you can try is to right-click on the system tray itself and 
unlock panels. Somewhere there is a dialog that allows you to add an item to 
the system tray. 

You can add program, applet, whatever, but again, it takes some searching. 
However, I avoid touching my system tray once I have it set up - not even 
what I'm telling you now - because it invariably messes up everything, and 
takes for ever to get it back. All my icons are shifted round, etc., etc., 
etc. .... And once you get it set, lock the panels, and leave your tray 
alone! 

Also you can add a quick launch folder to the tray. 

If this doesn't work, then I must wonder if there is not some other issue. 
Another oddity: I did a quick search using apt-get, and mathpix doesn't come 
up. I am running Devuan Jessie, so maybe it's just not in those repositories.
