Xcode Storyboard - how to seamlessly change from one scene to another

The only transition I know so far is a segue - which makes another View Controller window pop up.
However, I'd like for a new scene to load within the same View Controller/UI frame upon the click of a button.

How can this be done for MacOS?
(Sorry, I was missing the word macOS.)

You can find some old threads for macOS.

Some examples:

Can't you find anything useful in any of them?
