getAccessToken fails in Outlook plugin with error 13006

Question

I was previously able to call Office.auth.getAccessToken in the Outlook 365 client from a taskpane plugin. However, I have switched to the 'new' Outlook and this call always fails with error 13006.

As an alternative, I have tried the display dialog method discussed in the documentation. This works fine but it constantly asks the user for permission to open the authentication dialog box. This is clearly not acceptable.

Is there a reason why getAccessToken doesn't work in the new Outlook?
