last message(read details)

you should add a button that brings you back to the last message that you had sent if you were gone for a while. say your part of a hyper active group, and you wanted to see what they had talked about after you had left, but they text way more than any human person should, and you would spend hours trying to find where you left off in the group chat, so when you press the button it can bring you back to the last message that you had sent.
