Make the phone app have an option to choose custom ringtone for incoming chats
It will be good to choose custom ringtone from your phone so you can make it like someone is calling you when there is incoming chat.

Is there a tool to set a custom tone for a group of contacts? We have a college group where we chat and share homework exercises in writing https://www.writemyessayfast.ca for our Langara College project. Please add this feature.
