Message Only Extension and IVR

Hello, we recently ported all our numbers to Zoom and everything seems to be performing as expected, with one exception.  We had a message-only extension with our previous provider, there is no phone number assigned to the user, who has a basic Zoom phone license assigned.  

I set up our IVR, assigned a placeholder user extension and now want to edit that to ring the voicemail extension.  When I try to set the key action as Forward to User I receive this error message "This feature requires a Zoom Phone Metered, Unlimited, or Pro plan.
