With the recently released July 2018 Hotfix (AKA Mid-year Canadian Update-English) KB4099101 you can now, optionally, use Organization Accounts from your Azure Active Directory for the following GP 2018 Workflows roles:

  • Originator
  • Approver
  • Manager

Because this new functionality allows more clients to use Workflow and because the Azure portal has changed lately Microsoft recently published a new blog on Creating the Azure Active Directory and Application with Dynamics GP in mind.

You may find that blog by Lucas Miller HERE.
