You can enable screen pops however it can only be done with R9. Within One-x (user, not admin) you would select "Configure", then "Notifications" and select "Enable IM Desktop Notifications". Once this is done, you will need to configure the browser to allow the screen pops to work with One-X. I apologize but I do not have specific directions offhand for that although I do recall Chrome being the easiest to set up.
