Hi Jean Lanza
To grant an application access to Machine Learning Services in Azure, you need to assign the appropriate permissions to the app registration. The permissions relevant to Machine Learning Services include actions like registering the subscription, updating quotas, and reading quota and usage information.
You can manage these permissions through Azure Role-Based Access Control (RBAC) by assigning a role that includes the necessary actions for the application. For example, you might consider assigning the "Contributor" role, which typically allows for full access to manage resources, or a more specific role if you need to limit the permissions.
