Adding List Icons to Latest Posts Widget in WordPress

We use a widget called Latest Posts on the sidebar of our blog. But posts are shown without any list icon. You can get a glimpse of this in the sidebar of this page https://financebenz.com/hdfc-swiggy-credit-card.html
We want to show these posts with a list icon but we do not find any option for this in WordPress or your theme. We want this list to appear like the image shown below.

Please help us with this.
