How to set up google authentication in asp.net core api-CodePudding

I am new to asp, On front end I have react and I want to authenticate users using external login providers. I have obtained client Id and secret from google.

builder.Services.AddAuthentication(auth =>
{
    auth.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    auth.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
    var key = Encoding.UTF8.GetBytes(builder.Configuration["AuthSettings:Key"]);
    options.TokenValidationParameters = new TokenValidationParameters
    {
        ValidateIssuer = true,
        ValidateAudience = true,
        ValidAudience = builder.Configuration["AuthSettings:Audience"],
        ValidIssuer = builder.Configuration["AuthSettings:Issuer"],
        RequireExpirationTime = true, 
        IssuerSigningKey = new SymmetricSecurityKey(key),
        ValidateIssuerSigningKey = true
    };
}).AddGoogle(googleOptions =>
{
    googleOptions.ClientId = builder.Configuration["Authentication:Google:ClientId"];
    googleOptions.ClientSecret = builder.Configuration["Authentication:Google:ClientSecret"];
}); ;
