API to fetch Application usage from the devices managed by Intune

Using Graph API's we can fetch the devices registered with Intune account, we can fetch the apps installed on the device (detectedApps) as well.

API to fetch Devices - GET https://graph.microsoft.com/v1.0/devicemanagement/manageddevices
API to fetch apps on Device - GET https://graph.microsoft.com/beta/deviceManagement/managedDevices/{deviceId}?$expand=detectedApps

We don't have any API to fetch the usage/activities of the applications on the device; example - when the application has been accessed on the device, what actions are performed on the application, etc.

This API will provide the auditing of analysis purpose to track the usage of applications from device.
