Xcode – Stack Hides Behind Tab Bar in SwiftUI

I am new to SwiftUI and using a tab bar. Inside my tab bar there are 4 views, of which I made different class for each. Now I am using a VStack for the rectangles but these rectangles hide behind the tab bar. I am attaching screenshot for this:

and here is my code:

struct ReportIncidentView: View {
    var body: some View {
        
        ZStack(alignment: .bottom) {
            LinearGradient(gradient: Gradient(colors: [Color(ColorName.gradient1.rawValue), Color(ColorName.appBlue.rawValue)]), startPoint: .top, endPoint: .bottom)
         
            VStack(alignment: .leading) {
                
                Text("Start Questionairre")
                    .foregroundColor(.white)
                    .font(.custom(InterFont.semiBold.rawValue, size: 30))
                    .padding()
                
                VStack(spacing: -1) {
                    
                    NavigationLink(destination: HitandRunView()
                                    .navigationBarBackButtonHidden(true)
                                    .navigationBarHidden(true)
                    ){
                        reportIncidentsView(text1: "Car accident", text2: "Report accident here", corners: [.topRight])
                    }
                    
                    Rectangle()
                        .frame(height: 2)
                        .foregroundColor(Color(ColorName.emailColor.rawValue))
                    
                    NavigationLink(destination: HitandRunView()
                                    .navigationBarBackButtonHidden(true)
                                    .navigationBarHidden(true)
                    ) {
                        reportIncidentsView(text1: "Crime incidenct", text2: "Report crime here", corners: [])
                    }
                }
            }
       
        }.ignoresSafeArea()
    }
}

Can someone tell what thing has to be done so that it can come up the tab bar?
