I know that the documentation for this says that it cannot be edited but surely there are plenty of use cases for this. For instance, if an employee mistakenly inputted the subdomain in IAM Identity Center or if a company was rebranding, there would need to be some way to change the login address.
One workaround that I'm considering is to delete our entire IAM IC configuration and rebuild it from scratch. Would this work? Obviously I would rather not do this but from what I'm seeing it's our only option.
