Outlook for Mac - Upload and Share is not working as access "Recipients of this message" is missing

New Outlook for Mac has since some versions back gotten the feature where the user can upload a file and share it to the recipients of the e-mail. The file will be per default be uploaded to DOWNLOAD folder in OneDrive.

Now this is not working on Outlook for Mac as the whole access permission Recipients of this message" is missing. On Windows and Outlook on Web, this is available, but not for New Outlook for Mac.

It seems that this feature is not yet fully developed on Outlook for Mac.

Any others that see the same and can confirm?
