It would be great to have an Azure Integration that pulls in information about the client's resources in their Azure subscriptions. A simple list of resources would be amazing.

Azure Lighthouse provides MSPs with delegated access to customers' Azure subscriptions. This has to be configured separately from GDAP. In the end, all MSP engineers can access all customers' Azure subscriptions/resources using their accounts. Intergrations can also employ this through an app registration, and can be configured to provide read-only access to all the subscriptions for ingestion into Hudu. https://learn.microsoft.com/en-us/azure/lighthouse/overview We currently have Azure lighthouse working with BackupRadar, so we know it can work with a single set of credentials to access all customer subscriptions.
