How to run two PowerPoints simultaneously with a virtual desktop?

When making a presentation using MS PowerPoint, it would be very useful if two or more could be displayed simultaneously. 

This was not possible before, but it is said to have been possible since Microsoft Office 2019 with virtual desktop.

The operation method is as follows. 

1. Create Windows Virtual Desktop

2. Run the PowerPoint program on one desktop.

3. Run another PowerPoint process (shift + click, etc.)

4. Go to the virtual desktop change screen with the win+tap key

5. Move one of the processes executed in number 3 above to drag and drop to another virtual desktop.

PPT presentations have now been executed on each of the two virtual desktop screens!

When you present, switch to the control key + window key + direction key and continue the presentation to the screen you need.
