remove Goodreads Widget

Hi, I installed the Goodreads Icon to my webpage today and now realize it doesn’t work on WordPress. Can someone tell me how to remove it from my page. When I went back to my site, under appearance, I can’t even find the list of other social media icons. Please advise. Thank you. p.s. Perhaps this was a problem for some one else, because i saw it as a question four years ago, and that was topic has since been closed.
