Critical bug when using Headers

[JP-902130]

There is a serious issue when we want to include a header in this chat ui. I tried multiple approaches:

1. I tried to use the built-in react native navigator header. That will cause the keyboard problem in IOS
2. I tried to build my own header, then in Android, the screen will jump when I navigate out of the chat room

Thank you so much for looking into this

Hey @Justin-Jingcheng-Peng as you can see by the commit history, this is super outdated and not maintained. Unfortunately I have no time to do it now, so please look for the alternative, thank you.
