❔ Blazor WebAssembly: How to dynamically hide a layout component after logging out

Question: I have a Blazor WebAssembly application where I'm using the MudBlazor library to create a layout that includes a navigation bar (MudAppBar). I want to dynamically hide this navigation bar after a user logs out of the application. Here's the relevant part of my layout:

@if (AuthState != null && AuthState.User.Identity.IsAuthenticated)
{
    <!-- MudAppBar and other layout components -->
}
else
{
    <!-- Layout without MudAppBar -->
}

@if (AuthState != null && AuthState.User.Identity.IsAuthenticated)
{
    <!-- MudAppBar and other layout components -->
}
else
{
    <!-- Layout without MudAppBar -->
}

I'm triggering the logout process using the following code:

private async Task<bool> SignOut()
{
    var isLoggedOut = await _JwtAuthProvider.Logout();
    if (isLoggedOut)
    {
        _navigationManager.NavigateTo("/login");
    }
    return isLoggedOut;
}

private async Task<bool> SignOut()
{
    var isLoggedOut = await _JwtAuthProvider.Logout();
    if (isLoggedOut)
    {
        _navigationManager.NavigateTo("/login");
    }
    return isLoggedOut;
}

Inside my Logout method, I'm using NotifyAuthenticationStateChanged to reset the authentication state and set it to an empty ClaimsPrincipal. However, after navigating to the login page (/login), the navigation bar (MudAppBar) is still visible. It seems that the main layout is rendered when _navigationManager.NavigateTo("/login") is invoked. How can I ensure that the navigation bar is hidden after a user logs out and navigates to the login page? Is there a way to dynamically update the layout based on the authentication state without requiring a hard refresh of the page? I appreciate any insights or suggestions to resolve this issue. Here is my custom AuthenticationStateProvider - how i user NotifyAuthenticationStateChanged - -> check the Logout() method. https://paste.mod.gg/kvvtgasbzsxo/0
