Checklist

• I fully tested it as developer / designer and created unit / integration tests
• I documented it (or no need to document or I will create a separate documentation issue)

How to test it?

Run the app template.

context.Services.AddAuthentication()
        .AddGoogle(GoogleDefaults.AuthenticationScheme, options =>
        {
            options.ClientId = ".......";
            options.ClientSecret = ".......";
        });
