Changing Keybindings in The Sims 4

I had a mouse that had the battery area kinda broken and it would go out like it was dead and id have to use tweezers to put the wires in place and then the battery in there in a special way and wait til it eventually needs me to do that again. So i bought a 30$ mouse on Amazon that looked like it was a lasting one, the stuff it was made with and the features, then like 3 days after i get it, i was scrolling and i set it aside and as i lifted my finger all the way up i heard a weird sound and it kinda sunk and my finger followed it down lightly. Then i realized it wasn't scrolling and when i tried the scroll wheel made a raspy sound like it was stuck so i tried to fix it, i fixed some of the weird sound it made to make it sound normal but like there isn't much i can mess with on the mouse since its made to prevent people from breaking into it and * it up like a child or something getting into it while you are at work. So anyways, basically i can't afford to buy a better, and this time, brand name mouse that i can like rely on. I lost my other mouse with the battery issue, so i need to like configure sims to make the button on the side of my mouse scroll in, while the button behind it can scroll out since the mouse is really easy to control all buttons on it when using it. ☹️ ugh
