Razer Basilisk third button program?

Hello, I just bought the razer basilisk mouse and I'm on a mac. This mouse features a thumb button. It seems to work when I press and hold it. The default action for it is to move the mouse slowly. I want to remap this functionality to Mission Control. When I'm in BTT and setting up a mouse action, it does not detect me clicking the button but it detects all other buttons. Is there a way to debug this?
