Take a look at some of the messages in the Debut forum. I was able to use it a couple of times and it worked really well, but I found once the trial period ended it didn't work anymore. I think other people have had similar issues. There may be a way around it, but I never followed up as I realised that I can use PowerPoint. You may also be able to use the Game Bar in Windows 10, although that didn't work on my hardware.
