    new OpenIdConnectAuthenticationOptions
    {
        ClientId = clientId,
        ClientSecret = clientSecret,
        Authority = authority,
        PostLogoutRedirectUri = postLogoutRedirectUri,
        ResponseType = OpenIdConnectResponseType.Code,
        RedeemCode = true,
        RedirectUri = redirectUri,
        UsePkce = true,
    });
