Add Separate (or customizable) Notification sounds for chat/phone

My team is having trouble meeting SLA targets as they use both phone and chat. it would be great to have a different notification sound that alerts them when chats are assigned to them, as they are working on multiple monitors, and its easy for them to miss it while they are working. Browser notifications are too broad, and it would be great to have something native in Intercom to make it easier for them.
