What launcher / home replacement are you running? If its Nova, long press on the desktop and choose "nova actions" - then choose app drawer, once the shortcut is created you drag it to your tray.
If its another launcher it probably has a similar ability to create action shortcuts. Someone else will have to chime in on your particular version as I don't know how Apex or other launchers handle it.
