My website How do I get the thumbnails to show up when the article links are shared on Lemmy? I tried metatags, changing the aspect ratio and the image format. Nothing seems to work. Here are some of the failed results.: [email protected] Any help would be appreciated.

Article.tsx:

import { useParams, Link, useNavigate } from "react-router-dom"
import { articlesData } from "../data/articles"
import { styled } from "styled-components"
