How do I enable Login via Netlify Identity?

[facinick]

I want to enable Only Login via Netlify identity, which has email and google login options.
How can I incorporate this change in this repo?

as of now it's only showing me an email password form.

my config.ts shows this:

cms_manual_init: true,
  backend: {
    name: 'git-gateway',
    repo: 'facinick/[my-repo-here]',
    branch: 'master',
  },

I have enabled git-gateway and netlify identity in my netlify dashboard
