Custom Sidebar on Category Page

Hi,

Wondering if there’s a method to have Custom Sidebars appear on category pages (where multiple posts appear on a page rather than a single page or post.)

Trying to get the custom sidebar I created and which appears here: https://www.uschillel.org/uschillel/jewish-trojan-family/usc-hillel-art-gallery/

to appear on this category page: https://www.uschillel.org/uschillel/category/current-events/

Thank you!

The page I need help with: [log in to see the link]
