Change View Swift ui - ios

Question

the swift code below represents two views the first that is displayed is home with the login button and the register button, what I have to do is that when the SIGNUP button is clicked the push to the HomeView view which contains the MapView, practically I have to push to the new view with the click on signup, but with the navigationlink this does not show me the view, how do I solve this?
Home.Swift
import SwiftUI
import MapKit
struct HomeView: View {
#State private var userTrackingMode: MapUserTrackingMode = .follow
#State private var region = MKCoordinateRegion(
center: CLLocationCoordinate2D(
latitude: 25.7617,
longitude: 80.1918
),
span: MKCoordinateSpan(
latitudeDelta: 10,
longitudeDelta: 10
)
)
var body: some View {
Map(
coordinateRegion: $region,
interactionModes: MapInteractionModes.all,
showsUserLocation: true,
userTrackingMode: $userTrackingMode
)
}
}
struct HomeView_Previews: PreviewProvider {
static var previews: some View {
HomeView()

}

if UIScreen.main.bounds.height > 800 {
Home()
}
else {
ScrollView(.vertical, showsIndicators: false) {
Home()
}
}
}
}
