How to create Radiobuttons in SwiftUI?

Question

I would like to react on a choice of a user. Something similar to this example:

In a 2nd stage would I like to show additional content below each radiobutton, e.g. moving the buttons 2 and 3 from each other in order to give a list of websites for allowing.

So far I haven't found how to do this in SwiftUI. Many thanks in advance!
