Is it possible to bind mouse 4 btn to a specific key on the keyboard on MacOS? I bought a cheap USB mouse with 2 additional buttons, the ones that you can click to go back and forward when surfing etc.

I'm wondering if it's possible to bind one of those mouse buttons to another key on the keyboard?

Scenario:
I press mouse 4, and it clicks on number 1 on the keyboard.

I'm on MacOS Sierra.
Steermouse is another way to enjoy this functionality.
