In this article, you create a back-end service that adds desired properties to a device twin and then queries the identity registry to find all devices with reported properties that have been updated accordingly. Your service needs the service connect permission to modify desired properties of a device twin, and it needs the registry read permission to query the identity registry. There is no default shared access policy that contains only these two permissions, so you need to create one.
