AddOidcAuthentication in blazor Web App .net 9

I added the Oidc Authentication in blazor client project but it shows error
IAccessTokenProvider Not Registered.

I want to get the access token into HttpClient as authorization header bearer token.

namespace ClientThree.Client;

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.WebAssembly.Authentication;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading;
using System.Threading.Tasks;

public class OidcAuthorizationHandler : DelegatingHandler
{
    private readonly IAccessTokenProvider _tokenProvider;
    private readonly NavigationManager _navigation;

    public OidcAuthorizationHandler(IAccessTokenProvider tokenProvider, NavigationManager navigation)
    {
        _tokenProvider = tokenProvider;
        _navigation = navigation;
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        var tokenResult = await _tokenProvider.RequestAccessToken(new AccessTokenRequestOptions
        {
            Scopes = ["api"] // Match the scopes your API requires
        });

        if (tokenResult.TryGetToken(out var token))
        {
            request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token.Value);
        }
        else
        {
            // Optional: Redirect to login if token is not available
            _navigation.NavigateTo(tokenResult.InteractiveRequestUrl);
            return new HttpResponseMessage(System.Net.HttpStatusCode.Unauthorized);
        }

        return await base.SendAsync(request, cancellationToken);
    }
}

Program.cs client  

builder.Services.AddOidcAuthentication(options =>
{
    builder.Configuration.Bind("Oidc", options.ProviderOptions);
    options.ProviderOptions.DefaultScopes.Add("api"); // match API required scopes
});
builder.Services.AddHttpClient("ApiClient", httpClient =>
{
    httpClient.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress);
}).AddHttpMessageHandler<BaseAddressAuthorizationMessageHandler>();

builder.Services.AddScoped(sp => sp.GetService<IHttpClientFactory>().CreateClient("ApiClient"));

builder.Services.AddScoped<IWeatherForecaster, ClientWeatherForecaster>();

@using Microsoft.AspNetCore.Components.WebAssembly.Authentication
@inject IAccessTokenProvider TokenProvider
@page "/AccessToken"
@jwtToken
@code {
    string jwtToken;
    protected override async Task OnInitializedAsync()
    {
        var result = await TokenProvider.RequestAccessToken();
        if (result.TryGetToken(out var token))
        {
            jwtToken = token.Value;
            Console.WriteLine(token.Value); // JWT
        }
    }
}

what is the missing in the code?
