Configuring Mouse Button to Minimize Window

Hi all,

Just got the Razer Basilisk x Hyperspeed, and looking to configure the mouse buttons. For the default "Cycle Up Sensitivity Stages" button, that's where I normally configure the button to "Minimize Window". However, I can't seem to find the right setting to configure the mouse button. How do I go about doing it?

This is what I've tried so far:
1. Checked under Windows Shortcuts - no option to minimize window here
2. Tried using Keyboard Function->Key Recording to record a shortcut to minimize windows
- The two short cuts I found online are "Win + Down Arrow" and "Alt + Space + N"
- First of all, on my PC, for some reason "Win + Down Arrow" doesn't minimize my window. Instead it, restores my window. Second of all, the key recording function doesn't record the Win button every time I to record. So it just results in the "Down" button

- For "Alt + Space + N", the key recording cannot record 3 keys (seems like there's just a maximum of two), so I can only record either "Alt + Space" or "Alt + N", both of which are useless to me.

Is there any solution for me to configure my button to a "Minimize Window" function? Any advise would be much appreciated.
