Allow notification sounds to bypass silent mode from one app

Hello,

I work in an office that has recently installed a doorbell system that uses an App to activate the camera and communicate with guests. In order to hear the doorbell, my phone can't be on vibrate. However, if I leave my phone sounds on, then all notifications, rings, etc., come through, and this can be disturbing when I'm in meetings with other people.

Is there a way to permit sounds from one app only to (or to pick and choose apps), that will ring even when the phone is on silent? I know this works for the Alarm app. I looked into the Do Not Disturb option, but that only allows certain contacts to bypass the Do Not Disturb function, not specific apps.

Any suggestions?

Thanks for your input!
