How to capture your on-screen steps on video with a builtin windows feature ?

Found myself wishing to send a short video demonstrating some steps to a friend. But did not like the idea of making a bundle of screen snips. A video would be much more convenient, I thought.
I Started considering 3rd party options in windows, but then I thought that maybe windows has a built-in option (linux has such a built-in option I should write about some day) and was happy to search and learn that it has - the Windows Game Bar, an app that makes it simple, among other activities, to capture clips of your screen activity:

Win+g will open the Windows Game Bar:

Start recording using the "record" button (black arrow pointing):

While recording a small status and control window shall appear, and with which you can stop recording:

Find the folder with the media created, using the folder button (black arrow pointing):

And in it you shall see an mp4 file, named after the name of the window that was active, when you pressed the win+g activation.

p.s 

I tried but could not find a way to start the Windows Game Bar directly. Only Win+G. If anyone found a way - will you drop me a line, , please?
