What is the purpose of "DetailedErrors" in the default appsettings.Development.json file for a Blazor Server App?

Using Visual Studio, I created a Blazor Server App with the following default options:

This creates the following appsettings.Development.json file:

{"DetailedErrors": true,"Logging": {"LogLevel": {"Default": "Information","Microsoft.AspNetCore": "Warning"    }  }}

I have searched the app for any mentions of a DetailedErrors and the only result is where it is defined in the appsettings.Development.json file.

Can someone explain what "DetailedErrors": true is doing if anything?
