Help removing Grohe Carlton volume control handle

[TheLix]

Anyone know how this Grohe handle comes off? I'm assuming the plastic cover comes off to expose the screw but I can't get it to budge? I was able to get a thin flat screwdriver under the edge but it won't move. Since it is a 2004 model I really don't want to damage the cover since I probably won't be able to get another.

i think the cover comes off by rotating/un-screwing

Looking around, it looks like this might be a Hansgrohe Carlton valve (as I understand, they are separate companies).

Is there a plug under the valve, where a screw might be?
I know it's not exactly yours, but this drawing seems to imply some sort of screw at the bottom. Possibly once that is off, it then pulls off?

There's also this, which seems to show a possible screw hole cover?

The handle looks the same, but the dome part does look a little different, so I don't know 100%.
