Does the WWDC Student Challenge playground need more than one page? I connected my screens within one page of the playground. I have finished creating an Xcode Playground, and I was wondering if I had to separate it into multiple pages. Thanks!

Link to code: luca-jon.medium.com/create-an-inset-grouped-list-in-swiftui-for-macos-20c0bcfaaa7 I used the code from this post. Am I allowed to use it in my project? Do I have to select YES for the, "Did you use open source software?" question, if I use it. I also see that this code is hosted on GitHub, so it open source? Thanks!
