I'm training new staff for the first time in several years; and we're using the Ring Central Desktop App which is nice. But, it doesn't have HUD. This feature is ESSENTIAL when training telephone support staff. Especially now that no one is in the same office with anyone else. It's absolutely ESSENTIAL to be able to monitor who's on a call and then to "monitor" that conversation so managers can coach or take over the call. I installed the old Ring Central Phone App along side the new one for now. But, please add HUD to the Ring Central Desktop App.
