RingCentral App for desktop will not show contacts in Manually Created Outlook 365 Contact Folders by Users

I have several users who organize their Outlook Contacts by creating additional folders in Outlook. When contacts are added to these folders, they do not show up in the RingCentral App (desktop version). They do show up in the RingCentral mobile app however. Thus, they are hitting the RingCentral system, but the RingCentral desktop app will not show them.

Would like this feature added to the RingCentral App for desktop.
