Guide button for Android box

I have just set my X1 up to control my LG OLED65CX, Yamaha RX-A8A, and Android box (the latter via Bluetooth). The Android box is our cable company's version (Cogeco Epico) of a Sagemcom DIW3930 and its remote has dedicated Guide and Menu buttons. The generic X1 Android box setup does not have a Guide Button and the Menu button doesn't do anything on my box. I can reassign the Menu button to Homepage which works, but can't find a direct button press to get to the Guide. Any help?
