I am attempting to deploy workflow manager through ArcGIS Online. I am an admin in my AGOL organization. When I go to Organization -> Licenses and scroll down to Workflow Manager, I see that there are zero compatible user types for this extension.

But when I click "Manage", I see a message that the user type professional plus already includes a license for Workflow Manager:

When I attempt to access the workflow manager web application, I see an error message that workflow manager is not licensed:

Do I need to do any licensing steps through ArcGIS Pro? Do I need to add different user types to use this extension? Any direction is appreciated.
