Using Apple Configurator 2, do I need to be enrolled in the 'device enrollment program' to supervise my device?

When I try to prepare a device in Apple Configurator 2 (2.7.1) (manual setup, supervise devices, Do not enroll in MDM ), I am asked to sign in to the Device Enrollment Program, and since I'm not part of it I get an error when I sign in with my apple id:

<email> cannot access the Device Enrollment Program. Please contact your organization’s administrators.

I have supervised devices before with an older version of Apple Configurator, is this a recent requirement?

Is it no longer possible to manually supervise a device without enrolling en the 'Device enrollment Program'?
