Whitelist for domain name with Google Login

## Problem

For supporting Google Workspace login

## Appetite

> How much time do we want to spend and how does that constrain the solution? (Usually 2 weeks or 6 weeks)

## Solution

Need some research to see is it better to:

1. White list domain name of login email
2. Or is there specific Google Workspace Login apart from General Google Login?

## Success definition

Allow users to easily add support for Google Workspace Login

## Rabbit holes

> Details about the solution worth calling out to avoid problems

## No-goes

> Functionality or use cases we intentionally aren’t covering to fit the appetite

No files, tests, or entry points are named. Start by researching whether Google Workspace requires a distinct Google login flow or whether restricting login email domains is sufficient, then inspect the existing Google Login integration. Done means selecting an approach that lets users add Google Workspace login.
