              You can definitely implement something similar. (That is a hosted Discourse community too)
As a starting point I would use the “Boxes with Subcategories” desktop category page style.
Then your box will look similar to this one

You can also add a category logo in the category settings

Then you can add some CSS to style it the way you like
Tip: you can not only inspect your forum but also your example
