Aiming to surpass or at least meet the level of polish in this chat demo, improve the chat input, submit button, and record button, and chat message list.

We don't need to copy the demo, we just need to get it to a similar or better level of polish. Having our own style is better. :)

Notice in the inspiration demo that the record button is not near the chat. Use your discretion for where to place the microphone/record button, feel free to modify the layout if desired, etc. The main goal is to take inspiration from the level of polish, but not literally copy it.
