Bypassing "Pick user popup" after Sign out in a .Net 8 Blazor WASM application

Question

How can I modify the logout code in my .Net 8 Blazor WASM application to include the logout_hint parameter? I have already enabled the login_hint optional claim in my client application and have the value of the logged-in user's login_hint optional claim. Here's the existing code:

@code{
    private async Task BeginLogout(MouseEventArgs args)
    {
        await SignOutManager.SetSignOutState();
        Navigation.NavigateTo("authentication/logout");
    }
}

Please advise on how I can bypass the "Pick user popup" after sign out.

Thank you for your post!

To hopefully help point you in the right direction when it comes to modifying your Blazor application's code to include the login_hint parameter and bypass the "Pick user popup" after sign-out, you should be able to reference the below.

// Construct the logout URL with the logout_hint and post_logout_redirect_uri parameters 

var logoutUrl = $"https://login.microsoftonline.com/{tenant}/oauth2/logout?post_logout_redirect_uri={logoutRedirectUri}&logout_hint={userId}"; 

var logoutUrl = $"authentication/logout?login_hint={userId}&post_logout_redirect_uri={logoutRedirectUri}&prompt=none";
