How to connect blog thumbnails to blog posts?

Hi,
We are trying to make a blog page. One page will have all the blog thumbnails and clicking on them, it will take the viewer to the actual blog posts. Made the thumbnails using CMS following this tutorial Building a Webflow CMS Blog | Step-By-Step - YouTube But in preview mode, the blog posts are not clickable. It doesn’t go anywhere if we click on the thumbnail. How to design the actual blog post page?
