Bonjour,
Veuillez consulter cette réponse:
"For first-party apps that are internal, you'll have something in both places - one to define the app (App registrations) and one to allow the app to actually sign in to Azure AD (Enterprise applications). When you define the first-party app in the App registrations, you'll also automatically create an entry in Enterprise apps. If you look at the two entries, you'll see that the Application ID links the two together."
J'espère que cela vous aidera.
Cordialement,
Nina
