Topic: Remote play app on PS5

Hi All
Does anyone know if you can remote play your PS4 from your PS5?
I've set it up the other way around and I know there's loads of info out there about remote playing the PS5 from the PS4, but I'm trying to get it to work the other way around, with no luck.

Maybe I'm being a donut. But this article does say this can be done

But in the games menu on my PS5, there's no remote play app?

Having the digital edition this would be really useful for the disc games on the PS4 I have. Also it's extra storage again.

Thanks for any help!
