I have stumbled on this modal today, and on the first loook, it seems like you are testing some appcues onboarding.
I know that modal styling is pretty annoying there, but please make sure the buttons actually responds and the user always have a possibility to close the modal with "close icon" – otherwise you are stuck and can't really do anything. For me it was adding users in the admin panel when I got stuck.
+ I have been using appcues myself for the last past month and a half, and if you want to talk about what's the best way to deal with this app, or how to use branching logic there – just let me know, I'd be happy to talk with you.
Perhaps a different use case here, but do you have any documentation or community articles on any kind of integration, perhaps via webhook, between AppCues and Marketo?
