Animate Change in SwiftUI ForEach Grid Using Array Indices

Does anyone know how I can animate a sorting change to grid items while iterating off of the array index in a ForEach?

I am showing a grid of items (LazyVGrid) from an array and the user can change the sort order of these items. When the sort order changes, I'd like to animate the change in the grid. This would work great if I were to use code similar to the following:

            Button {
                withAnimation {
                    noteModel.sortMethod = noteModel.sortMethod.next()
                }
            } label: {
                Text("Change Sort Order")
            }

            ScrollView {
                LazyVGrid(columns: columns) {
                    ForEach(self.notes, id: \.self) { note in
                        VStack {
                            Text(note.title)
                            Text(note.body)
                        }
                        .padding()
                    }
                }
            }

However, if my ForEach iterates off of the array index the change does not animate. So it won't animate if my code is similar to this:

            Button {
                withAnimation {
                    noteModel.sortMethod = noteModel.sortMethod.next()
                }
            } label: {
                Text("Change Sort Order")
            }

            ScrollView {
                LazyVGrid(columns: columns) {
                    ForEach(self.notes.indices, id: \.self) { idx in
                        VStack {
                            Text(self.notes[idx].title)
                            Text(self.notes[idx].body)
                        }
                        .padding()
                    }
                }
            }

Why don't I just do it the first way? The reason is because I found a great resource for dynamically adjusting frame sizes for items inside a grid (found here: https://swiftui-lab.com/impossible-grids/), but that requires the use of array indices in order to work. It's pretty cool and I am hoping I don't have to choose one or the other (dynamic sizing or animate changes).

Thoughts or ideas would be greatly appreciated. Thanks!
