SwiftUI Segmented Control Customizable

Question

I want to achieve such a control like this (https://github.com/Yalantis/Segmentio) in SwiftUI (but without image):

What would be the best approach?

Should I use a segmented control and customize it, like text in the middle and a bottom border?

Or should I use a ScrollView-->HStack-->XButtons?

This I already tried, but how should i animate the bottom border on selection change? Is something possible in SwiftUI?

ScrollView(.horizontal) {
    HStack(alignment: .center, spacing: 8, content: {
        Button(action: {
            print("Button pressed")
        }, label: {
            Text("Example Button")
                .padding(20)
        })
         ... button 2, ... button 3 and so on



     }).frame(height: 80, alignment: .leading)
}
