WKwebView in Swift Playgrounds(SwiftUI)?

How do I use WKwebView in Swift Playgrounds(SwiftUI App)
I tried to follow some tutorials but it seems like I am missing a critical file…..
Swift Playgrounds App

Thank you!
I don’t know if this is the right place…. I am a newbie(to this forum and SwiftUi)
Also, can I move an app from swift playgrounds to Xcode later?

Maybe I should just move the project to Xcode so it is easier?
