Get all detectedApp managed devices out of Intune

Question

We have a requirement to provide a report of all detectedApp with not just a count but rather all individual devices they are detected on.

We tried

GET https://graph.microsoft.com/v1.0/deviceManagement/detectedApps?$expand=managedDevices($select=id)

Against both v1.0 and beta but the response always contains managedDevices property as empty array:

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#deviceManagement/detectedApps(managedDevices())",
    "@odata.count": 1,
    "value": [
        {
            "id": "<SOME ID HERE>",
            "displayName": "MyAppName",
            "version": "1.1.0",
            "sizeInByte": 0,
            "deviceCount": 1,
            "publisher": "",
            "platform": "SOMEOS",
            "managedDevices": []
        }
    ]
}

Further, reading documentation on $expand that would be capped to 20 results only anyway.

Is there a way to get all managedDevices ids from ALL detected apps, not one by one?

When we do it one by one we keep hitting HTTP status code 429 for requests limits :(

Update

Using this request also returns an empty array under detectedApps

GET /beta/deviceManagement/manageddevices('<DEVICE_ID>')?$expand=detectedApps($select=id)
