Excessive notifications – Messenger Review

It would be really nice if the conversation I have open didn't give me a sound or vibration every time I get a message. I can't find a way to disable that. It makes it really hard to discretely message in a group setting. All I need is an alert to let me know I have an initial message, but once I am active in the chat it shouldn't keep alerting me every message.
