Interact with item inside widgets iOS14 - swiftui

Question

I am trying to create a medium Widget like in YouTube Music, but I am don't understand how to create an interaction with the particular item in a Widget. How my app should understand when user press on first or second item and then how I am must handle this action inside app. My app use Swift not SwiftUI, only for a Widget I use SwiftUI. In past I didn't have experience with a SwityUI.
My code for Widget:
struct WidgetTestEntryView : View {
var entry: Provider.Entry
var body: some View {
VStack {
HStack(spacing: 100){
Text("Favourite").foregroundColor(.white).font(.system(size: 16, weight: .bold, design: .default))
Image("Label").resizable().frame(width: 80, height: 15, alignment: /*#START_MENU_TOKEN#*/.center/*#END_MENU_TOKEN#*/)
}.frame(maxWidth: .infinity, maxHeight: 50, alignment: .center).background(Color.black).offset(y: -9)
HStack {
Spacer()
Button(action: {}) {
Image("").resizable().frame(width: 70, height: 70)
.cornerRadius(10)
.background(Color(red: 0.218, green: 0.215, blue: 0.25))
}.cornerRadius(10).onTapGesture {
let a = ViewController()
a.data.text = "Tap"
}
Button(action: {}) {
Image("").resizable().frame(width: 70, height: 70)
.cornerRadius(10)
.background(Color(red: 0.218, green: 0.215, blue: 0.25))
}.cornerRadius(10).onTapGesture {
let a = ViewController()
a.data.text = "Tap"
}
Button(action: {}) {
Image("").resizable().frame(width: 70, height: 70)
.cornerRadius(10)
.background(Color(red: 0.218, green: 0.215, blue: 0.25))
}.cornerRadius(10).onTapGesture {
let a = ViewController()
a.data.text = "Tap"
}
Button(action: {}) {
Image("").resizable().frame(width: 70, height: 70)
.cornerRadius(10)
.background(Color(red: 0.218, green: 0.215, blue: 0.25))
}.cornerRadius(10).onTapGesture {
let a = ViewController()
a.data.text = "Tap"
}
Spacer().frame(width: 10, height: 10, alignment: .center)
}.background(Color(red: 0.118, green: 0.118, blue: 0.15)).offset(y: -9)
}.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .center).background(Color(red: 0.118, green: 0.118, blue: 0.15))
}
}

You can do this using Link in SwiftUI.
Link(destination: url, label: {
// add your UI components in this block on which you want to perform click action.
}
url: Provide a unique string to identify widget action in the main app.
Now In the main app, use below method in AppDelegate.swift file:
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
}
In this method, you can identify the URL that comes from the WidgetKit action.
