Connecting to Realtime when entering a scene usng Connect()?

Super newb here! First, what I am trying to do. I want to give the user the chance to connect on scene start to a normcore room or not depending on whether they choose single or multiplayer. I have the UI working but the Connect() function seems to be always throwing reference errors. I found the API documentation for the Connect() method, but I cannot find an example of how to implement it (which probably reveals what a newb I am to Unity and/or C#). Also, am I correct in thinking that Realtime exists globally? So I could write Realtime.Connect(“Test Room”,null); from any start() on any object as longs as I am using the namespace Normal.Realtime? Or must the object itself have a Realtime script on it? If so, how to reference the Realtime object?
