I want to refresh a table list only when I receive push notification in swiftUI

I want to refresh my list using function call when I receive push notification. Earlier when I used observedobject list updating continuously and it looks like appear and disappear the list view continuously, now I am using stateobject , here list is refreshing only 1 time. ..I am very new in swiftui.Please suggest me how to refresh the else part each time when getting notification

MapviewUI:

**  @StateObject var viewModel = SettingsViewModel()
    @StateObject var vm = MapViewModel()
**
                if pushNotificationReceived == false {
                    ForEach(viewModel.users) { users in
                    NavigationLink(destination: ChatSwiftUIView(chatUser: users)) {
                        
                        VStack(alignment: .leading) {
                            
                            Text(users.email)
                                .multilineTextAlignment(.leading)
                        }
                    }
                    .padding(.horizontal)
                    .padding(.top, 8)
                }
                    
                }
                else{
                    
                    ForEach(vm.users) { users in
                    NavigationLink(destination: ChatSwiftUIView(chatUser: users)) {
                        
                        VStack(alignment: .leading) {
                            Text(users.email)
                                .multilineTextAlignment(.leading)
                        }
                        
                    }
                  
                    .padding(.horizontal)
                    .padding(.top, 8)
                }
                   }

                    print("Failed to fetch users : ", error)
                    return
