The next step requires a callback URL, which looks like this: `https://<project-ref>.supabase.co/auth/v1/callback`

- Go to your [Supabase Project Dashboard](https://supabase.com/dashboard)
- Click on the `Authentication` icon in the left sidebar
- Click on [`Providers`](https://supabase.com/dashboard/project/_/auth/providers) under the Configuration section
- Click on **{{ .provider }}** from the accordion list to expand and you'll find your **Callback URL**, you can click `Copy` to copy it to the clipboard
