How to pass additional @Binding parameters to the View from another parent View

[xplatsolutions]

I have a parent View with a TabView and a custom modifier to present a custom full modal view (doesn't exist in SwiftUI so custom work had to be done)

struct ContentView: View {
  
  @ObservedObject private var tabData = MainTabBarData(initialIndex: 1, customItemIndex: 3)
  
  var body: some View {
    
    TabView(selection: $tabData.itemSelected){
      // tab items with views and tags
    }
    .present($tabData.isCustomItemSelected, // Present the modal view when isCustomItemSelected @State is true
             view: Widget(store: HostBroadcast.ViewModel(), content: BroadcastLiveView.init), // Using CombineFeedbackUI Widget passing the viewmodel and content view
// I need somehow to link the isPresented: $tabData.isCustomItemSelected so that I can toggle it from the BroadcastLiveView to close the modal, or if feasible signal from HostBroadcast.ViewModel the state change to MainTabBarData
             style: .fade)

My BroadcastLiveView.init is following 0.7.0 tag source code examples.

  typealias State = HostBroadcast.State
  typealias Event = HostBroadcast.Event
  
  @ObservedObject
  var context: Context<State, Event>
  
  init(context: Context<State, Event>) {
    self.context = context
    logInit(of: self)
  }

I'd love to understand if this somehow can happen in ViewModel context, I have a Feedback where I check if the button to close the view tapped but I lack understanding how to tell the MainTabBarData ObservableObject that isCustomItemSelected should be false.

You can use context.binding(for: \.keyPath)
