Sending Rpc or Message to a specific client to change scene

I have a server scene and a client scene. As clients get connect to server, On server side it is added to a list .
Like a prefab is spawned in the list with client's name and a button.
I want to change the scene of an individual client when server hits the button of that specific client.

I got references like TargetRpc but don't exactly know how to use it.
