Different notification

As now the notifications for chat and e-mail are the same (for call and Whatsapp I dont know yet, have to connect it still). It would be better to have a different notification for each different channel. So the team knows what kind of ticket is incomming. 

My team has to react differently when a chat is incomming compare to an incomming mail. To respond to an incomming chat 2 minutes is to long, but for an e-mail its all good. As my team knows what kind of ticket is incomming by the sound, that would work way better.
