Linking a blog post title PLUS THUMBNAIL to another page

I have followed the instructions here: https://support.squarespace.com/hc/en-us/articles/206543297-Linking-a-blog-post-title-to-another-page

to link one blog post title to another page. 

However, this feature DOES NOT link the blog post thumbnail to the new URL in the summary.

How can I include the thumbnail in redirecting to the new link, whether through this method, URL mapping, or another way?

The blog post URL I want to redirect is: https://www.earthspeak.love/collective-courses-resources/heart-fire-activation-ritual

Thank you.
