TAdvGlowButton and Down Property

I'm trying to set the Down property of a TAdvGlowButton to True at design time, but it is fixed at False. Is there some other property to set to get it to work? I have tried to do this on many forms with various property settings, but no luck.

Using Sydney Patch 2 in Windows 10 Pro.

Set AdvGlowButton.Style = bsCheck

Ah, thanks Bruno.
