PS4 app - 2nd Screen?

For ages I have had the app and I will randomly check it to see if I can use it as a second screen.

I haven’t actually found any games that I have tried it wit where I can use it. I can imagine there can be some benefit at times or even if it’s just a cool feature but seems a little pointless if no games work with it.

Have you managed to use it with any games? If so, which?

Thanks!
