List Interactions

Hey Guys
So, In the sidebar, I want to create an interaction that, when the user clicks on “Document 1” it highlights in orange. That Part I did.
Then, when he clicks in “Document 2” (3…4, etc) this element gets highlighted and the previously selected one gets back to its initial state.

don’t worry about the other stuff that looks all crazy, the developer has to work them out, but I feel that this interaction I can do on webflow I just can’t figure out how…

Thanks in advance!
