Cannot find workbook relationship in a shareddriveitem/driveitem resource with Microsoft Graph API

Using Microsoft Graph API I am able to get the workbook resource from a driveitem that is stored on my business OneDrive via https://graph.microsoft.com/v1.0/me/drive/items/{id}/.

However, if another user shares the workbook to the organisation and I access it via https://graph.microsoft.com/v1.0/shares/{EncodedSharingURL}/driveitem/, I am not able to get the workbook resouce.

The response when trying to access the workbook of the shared driveitem is as follows:

"message": "Unable to find target address"

The JSON returned by the driveitem looks very similar in both cases. How is it different?
