Microsoft Edge Extension Auth0 implementation - Authorization page could not be loaded

The issue was that we hadn’t added the custom domain settings to our production tenant’s universal login page’s Lock config. Really wish the error was more descriptive.

Found from: Custom domain with auth0.js getting error "You should not be hitting this endpoint" - #2 by thameera
