[Bug] Not clear that users can hover over contextual results

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

Hovering over the embedding contextual results is an awesome feature that I found by accident when moving my mouse around.

How would we provide some reasonably clear indication to users that they can inspect the retrieved context by hovering over the left rail?

Expected Behavior

Users with minimal or zero RAG experience should be able to self-serve on this app to learn about the difference between RAG and Non-RAG pipelines.

Steps To Reproduce

Run the current version or hit prod.

The hoverable elements look like they are clickable. This is also a common pattern with similar tools like ChatGPT.
