List Closure not displaying retrieved data in Simulator UI

I have backend API caller file that retrieves and displays unwrapped JSON data via URLRequest(). All the data is printed to my console when I build the project but it's not being displayed in the actual UI of my iOS simulator.

I have a class in my ContentView that updates the UI and filters the extracted fields shown here below:

    
    class NotionCall: ObservableObject {
        @Published var extractedContent: [BlockBody.Block] = []
        
        func makeAPIRequest() {
            
            makeRequest { results in
                
                let extractedData = results.map { block -> BlockBody.Block in
                    var extractedBlock = block
                    extractedBlock.ExtractedFields = block.paragraph?.textFields.compactMap { textField in
                        textField.PlainText ?? textField.RichText ?? textField.content         //iterate over PlainText, RichText, and Content fields and return the non nill values
                        
                    } ?? []   //validate objects even if they are nil
                    return extractedBlock
                }
                
                
                DispatchQueue.main.async {
                    self.extractedContent = extractedData
                    
                }
            }
        }
    }
    
    
    @StateObject var NotionCaller = NotionCall()   //manage lifecycle of instance
    

And then below here is my SwiftUI structure that contains List(NotionCaller.extractedContent) { block in ForEach(block.ExtractedFields, id: \.self) { field in Text(field) meant to display the extracted data to the UI:

var body: some View {
        NavigationStack {
           
            
            ZStack {
                
                List(NotionCaller.extractedContent) { block in
                    ForEach(block.ExtractedFields, id: \.self) { field in
                        Text(field)
                        
                        
                    }
                    
                }
                
                ZStack {
                    
                    Color(hex: "#f9f9f9")
                        .ignoresSafeArea()
                    
                    
                    VStack {
                        
                        TextField("   Search keywords", text: $searchKeywords)  //change font later
                            .frame(height: 48)
                            .overlay(RoundedRectangle(cornerRadius: 30).strokeBorder(style: StrokeStyle()))
                            .foregroundColor(.white)
                            .background(.white)
                            .cornerRadius(30)
                            .padding()
                            .scaledToFit()
                            .frame(maxHeight: .infinity, alignment: .top)
                        
                    }
                    
                    VStack {
                        
                        Spacer()
                        
                        Divider()
                            .padding()
                        
                        
                        HStack {
                            
                            Button(action: {              //add functionality later
                            }) {
                                
                                Image("menuButton")
                                    .frame(alignment: .bottom)
                                    .padding(.horizontal, 42)
                                Spacer()
