Intune App inventory Graph

Hi All, 

I've enabled the configuration profile to receive app inventory data in Intune.

In the GUI the data I can view the data just fine, but I would like to use Graph to automate this data and create custom reports.

When I use the following https://graph.microsoft.com/beta/deviceManagement/managedDevices/[device-id]/deviceInventories('ApplicationProperties') I get an error: "Forbidden - 403 - 199 ms Either the signed-in user does not have sufficient privileges, or you need to consent to one of the permissions on the Modify permissions tab" even though the docs I can find about permissions are OK.
