The administrator audit log today tracks when a user accesses a model, which makes it useful for monitoring both unauthorized access/incorrect user settings and model usage across the platform. However, it does not log when a user accesses the model through NUX (which is not logged anywhere according to the support).
As an admin, I would like to see even these accesses be logged in the audit log. The benefit would be that I can continue to use the same source for security and usage monitoring, no matter what UX the model is using. Since every NUX page is linked to a specific model, opening a page could trigger the log event.
