Thanks for the feedback and experience! This is the difference between provisioning (adding an instance of an app to your tenant) and registration (Azure AD knowing your app exists). The pattern you're talking about is provisioning, and sadly yes, the manual route here is very focused on SAML. But anyone at all can register an app, and then anyone else can provision it into their tenant just by signing into it.

Will check out the docs and see what we can do, it's not good this was hard to learn.
