hi @Koslani you are pointing to element (circle) you are not able make change without custom JS code. When you check your live website with dev tools you can see that “current” tab link have class w--curent and attribute aria-selected="true".
You need to add click event listener to each tab check if classList.contains(“w–current”), if true remove background on all circles and set color to element (circle) with w--curent.
You can do identical thing checking aria attribute.
Your choice.
I am not aware how it will be possible do that “no-code” way with WF options
