Office365 Mail REST API: how to ignore ContentBytes in Attachments?

Question

I'm using Outlook Mail REST API to fetch messages, using get-messages API call.

I want to get the attachments together with message result, so I added $expand=Attachments to the call and it worked.

I don't need the ContentBytes fields in the attachment. So I'd like to find a way to tell MS servers to not send it. This will save bandwidth and CPU.

Is it possible to filter nested properties like Attachment using $select ? I tried $select=Attachments.Name,Attachments.Size but it didn't work.

我们可以将$select用于展开项，例如下面的请求：
