Ring Central Desktop App should work with Outlook for Scheduling

For whatever reason RC is phasing out the Ring Central video and using the desktop app directly. This is great however, users cannot see their scheduled meeting without having connected Google or MS O365. What about On-prem users? We do not have MS accounts. Now users cannot see their scheduled meetings. This should be an easy fix as when you do schedule a meeting, the software does open Outlook to send the invite.
