Propose New Meeting Time not supported by Office 365 Graph API

When you arrange a meeting and one of the attendees responds by proposing a new time, it is not possible to see the newly proposed time on the message object returned by the Office 365 Graph API.

Here is an example of the message object for such a response from the /messages endpoint:

        ],

Is this a bug in the Office 365 Graph API, or is there some other way of achieving this?

Thanks in advance!
