My boilerplate test app has this code LoginId | auth0-acul-js - v1.0.1, but the line “const loginIdManager = new LoginId();” throws the error “Universal Login Context is not available on the global window object.”
I have found some context as to why you might be facing the mentioned error and I believe you should be able to fix the issue by including optional data in Universal Login Context, as described here: Configure ACUL Screens. You should be able to use the Management API to make the configuration of context_configuration on this endpoint: Auth0 Management API v2
Ok after having another look, I now got something showing, turned out I needed to set Authentication Profile to “Identifier First” then something started to happen
