Corsair Harpoon RGB side buttons not working

So, recently, I purchased the Corsair Harpoon RGB mouse (as you could tell by the title).

While attempting to use the side buttons as keybinds in Fortnite (I was assuming that they would be displayed as MOUSE4, and MOUSE5), the buttons would not register into the slot.

Shortly after, I ended up downloading CUE (Corsair Utility Engine), which also did not work. I have tried remapping keys to register the side buttons as keystrokes, and a few other ideas, none of which seem to work. However, the lighting effects are working perfectly fine, which I guess indicates that the mouse and program are properly connected.



Any help would be appreciated, thanks.
