Display "username" by using message "id"

I have objects in this link, https://codepen.io/fdfd/pen/jOWQmmM?editors=0010
As you saw the object I have message sender and message receiver id. As you can see the image below, I already displayed those messages received by id_message_receiver: miti .
I am using reactjs (javascript)


My question is how to display the sender username as written on the image above?
If it is not clear, i will try to explain more.
