Microsoft Graph API DeltaLinks for Mailbox messages Not Returning Minimal Data on Changes

Delta query on users returns minimal data on changes using the header (Prefer Return = minimal).

Graph Explorer : https://graph.microsoft.com/v1.0/users/delta

C# : await graphClient.Users.Request().GetAsync();

But in the case of mailbox messages it returns all parameter, although using the header (Prefer Return = minimal).

Graph Explorer : https://graph.microsoft.com/v1.0/users/userid/mailFolders/inbox/messages/delta

C# : await graphClient.Users[userId].MailFolders[folderId].Messages.Delta().Request().GetAsync();

Is there any way to get the minimal data on mailbox message changes with delta query?

The Message delta documentation only defines a header for limiting the page size:

Each delta query GET request returns a collection of one or more messages in the response. You can optionally specify the request header, Prefer: odata.maxpagesize={x}, to set the maximum number of messages in a response.

If you want to track a specific set of properties, you can limit the response using the $Select query parameter:

You can use a $select query parameter as in any GET request to specify only the properties your need for best performance. The id property is always returned.

Only AAD resources support the Prefer: return=minimal header.
