In Visual Studio I am right-clicking on appsettings.json to bring up the context menu and selected the Properties option.
Nothing happened. I am on macOS. For a coworker who also has Visual Studio [and also on macOS] that same option brings up a dialog with various settings to customize. What might be happening here?

The
Propertiespanel is showing up now on the right hand side. I'm not aware of any particular change I made in the environment or project.
