Two synchronized lists

Hello. Can anyone tell me how to implement horizontal and vertical list synchronization in swiftui? For example, a horizontal list is a group, a vertical list is a row of groups. Example: drive.google.com/file/d/13CVnUYaf4zyD295LnDUFJ7aNLVKDfYvp/view?usp=sharing

Could you show the code you have tried, with a state var for each list ?
I haven't written the code yet, because I don't know how to do it right. I just have separate horizontal and vertical scrolling lists.
Code Block LazyVStack(alignment: .leading, spacing: 15, pinnedViews: [.sectionHeaders], content: {
                        if (tags != nil){
                            ScrollView (.horizontal, showsIndicators: false) {
                                HStack{
                                    ForEach(tags){tag in
                                        TagView(tag: tag)
                                            .onTapGesture(count: 1) {
                                                print(tag.name)
                                            }
                                    }
                                }
                            }
                        }
                        VStack(alignment: .leading){
                            Divider()
                            Text("Example")
                                .font(.system(size:19))
                                .fontWeight(.bold)
                                .padding(.vertical, 10.0)
                                .foregroundColor(textColor)
                            Divider()
                            if (rests != nil){
                                ScrollView(.vertical, showsIndicators: true, content: {
                                    ForEach(rests){rest in
                                            RestView(rest: rest)
                                    }
                                })
                                .padding(.top, 15.0)
                            }
                        }
                        .padding(.leading, 15.0)
                    })

I have a list in which there are groups, these groups should be above the vertical list in the form of a horizontal list, and if you scroll through the vertical list, then the top list automatically switches to the desired group
You should manage each scroll position in a State var.

Have a look here for example:
