How to replicate Weather on WatchOS

Weather app on apple watch has this button at top right that can change the viewing mode between Conditions, Temperature, Precipitation, etc. What kind of SwiftUI is this? Is this a custom UI with a button?

ChatGPT tells me to use SegmentedPickerStyle, which is not available in WatchOS

Picker("View", selection: $selectedView) {
    Text("Conditions").tag("Conditions")
    Text("Temperature").tag("Temperature")
    Text("Precipitation").tag("Precipitation")
}.pickerStyle(SegmentedPickerStyle())

I was able to replicate as below as a child of navigationStack

struct Example: View {
    @State private var showSheet = false
    var body: some View {
        // ...
        .toolbar {
            ToolbarItem(placement: .topBarTrailing) {
                Button {
                    showSheet.toggle()
                } label: {
                    Image(systemName: "ellipsis")
                }
            }
        }
        .sheet(isPresented: $showSheet) {
            List {
                // ...
            }
        }
    }
}
