Active app icon in panel behavior in Cinnamon

Hey there, on a previous Manjaro Cinnamon setup I had running I managed to play with my panel so that any app that was running on a selected monitor would be displayed after any of the panel app launcher icons. Additionally, if an app already had a launcher icon was running on the monitor in question it would simply change how the icon looked by adding a line underneath and generally displaying it in a “pressed” state.

I am setting up a new Manjaro now and for the life of me cannot figure out how to achieve this. I have managed to add a section for any open apps (window list), but it simply adds all of these to the launcher icons, it doesn’t fold them in, so to speak.

I am guessing it is something simple that is alluding me.
