Thanks a lot, I integrated your code and the button is working.

I am unsure about the vector origin part because I think the button glow disappears weather or not I put SetEntProp(dynamic_prop_button, Prop_Send, "m_glowEntity", -1); in it, so I assume it goes to
0,0,0 like stated in your source.

So for the glowing part I mark the thread solved.

Thank you for your help!
