Link to external URL with thumbnail/preview?

I've searched the Squarespace Help Guide as well as these forums but can't quite find an answer.

I have a client that wants to post a link to an external URL and have page title and image automatically displayed, as with shared links on other platforms like LinkedIn or Facebook. They don't need the Like/Share/Send features of those platforms but just want to easily drop a link and not have to jump through hoops to get the image and correct title.

The closest thing I see possible is Linking a blog post title to another page but that would still require adding and tinkering with an image.

Is this possible with an extension or plug-in?

Anyone have any ideas?
