A7815011 Mouse4 and Mouse5


I have this mouse (https://www.anker.com/products/variant/high-precision-programmable-gaming-mouse/A7815011).

When programming the buttons, I cannot seem to find MOUSE4 and MOUSE5 in the options. Are these missing, or am I just missing the menu they are in.


Looks like they are labeled Back and Forward for 4 and 5.
