Ability to control volume for Ring notifications for app

I wish there was a way to control the volume for the notifications on the Ring app, which are ungodly LOUD! While I turn my phone volume all the way down at bedtime, I still leave my volume on so that I can hear phone calls, text messages, etc. But when I'm sleeping, the Ring notifications are insanely loud. Even during the day if I don't put my phone on vibrate, I can getting crazy loud notifications when I am in meetings. I do want some low level audio as I do not want to ignore the notifications, but just not so loud that my ears bleed (over exaggeration for emphasis). Can you please allow us the ability to adjust the notification volume so that we can hear it ourselves and not everyone within 100 feet of our phones. Thank you.
