Where has the zoom and details slider gone? And how do I get it back?

This appears to be another UI issue for Garmin Basecamp. I have the latest version 4.8.9 on macOS 10.15.6. The details and zoom slider dialogue (and directions, I guess) has disappeared and I haven't thus far been able to find a key combination that gets it back. 

Any ideas?
