Create a new UserPool

This endpoint creates a new UserPool. UserPools associate a particular application with a group of users, and determines how those users are identified and authenticated via the authorization field. authorization should use the public JWKS URI of your identity provider. If you would like to use an idClaim other than the default sub, such as email, you may specify it here as well. If authorization is omitted, the UserPool will be configured as “Anon-hosted”. This means you can use Anon as your identity provider by issuing AppUserIdTokens from /org/appUserIdToken.
