Harlowe 3.1.0 - Drawing a Circle on the Background Photo

I used the css code below to incorporate a different background photo into specific passages. I’d like to circle something within that background photo for just one of the passages. Any ideas as to how I should go by doing this? Thank you!!!

Css Code:

tw-story[tags~="DACA-Story"]{
 /* Background for DACA Story*/
  background-image: url("https://images.axios.com/_BuKsTVML9o3TIlWB2RRt9PSQMc=/0x0:5255x2956/1920x1080/2019/11/12/1573586158785.jpg");
  background-size: cover;
}
