How to evenly space/center profile blocks

Site URL: https://www.roamvet.com/team

Hello, password for the site is "squarespace". I was hoping to center the two team members that we have so there isn't an empty blank space to the right. On the "team" page. Thanks so much!

You can use this to Website Tools > Custom CSS

@media screen and (min-width:768px) {
.user-items-list-item-container[data-section-id="672c6e4498dace27aa9ebf98"] li {
    position: relative;
    left: calc(~"50% + 50px");
}
}
