Mouse 4 and mouse 5 keybinds are unable to be mapped, glitched

Edit: A workaround I’ve had to do is remapping my entire mouse just for the game and assigning the mouse buttons to keyboard keys. If your mice have this function, it’s the literal only way to use M4 and M5 right now. The downside is that you likely have to manually reset your buttons for any function outside of the game once you’re done.
