@microsoft.graph.downloadUrl availability in the driveItem delta response

[Tony-Dev07]

Hello,

I’m using the Microsoft Graph API delta query on the root of a drive:

GET /drives/{drive-id}/root/delta

I have a few questions regarding the @microsoft.graph.downloadUrl property in the delta responses:

For file items returned by the delta query, is @microsoft.graph.downloadUrl always included?

Are there situations where it might be missing, even if the file has changed?

Thank you in advance.
