User initiated screen recording on macOS.

I've just finished watching the "Capture and Stream apps on the Mac with ReplayKit" session. It is very informative! I am wondering if it's possible for an end user to start a screen recording that utilises ReplayKit on the Mac.

On iOS, Control Centre allows a user to start a screen recording or broadcast. I'm aware the Mac has a method of taking a screen recording (Grab.app or Shift-Cmd-5). This doesn't record the system or app audio unfortunately. It also doesn't present a broadcast picker. Is this intended behaviour?

I would love to be able to use the great features of ReplayKit on the Mac, just as I do on iOS.

Many Thanks, Celso
