I just quickly explain what the default redirect url is for. The default use case is that a user opens an application, the application makes an authorization request to zitadel, zitadel authenticates the user and redirects back to the requested redirect url (requested in the authorization request and configured on your application). The default redirect url is for all the usecases where ZITADEL doesn't have a authorization request from an application. e.g. password reset, user activation, so ZITADEL redirect to the default redirect url instead.
