create a list from selected items in a "Add to playlist" style

I'm looking for a way to create a list from items from another list by selecting items in SwiftUI The way it works in my head is that when I Touch the button "Add to list", an external screen pops open from the bottom with a list of names (imported from a csv file) and I can select names by touching on a plus sign in that name and it automatically adds to the list in the first screen. I can only find tutorials on how to write something in a textfield but and add that typed text into a list but no tutorial on the one I've discribed above. Can anyone help me out?

If you could show as much code as you could, more readers would try to help.
