The query [1] will list all users with samlIds in the org, but how can I craft the query to search for a user with a specific `login`? [1] ``` query Users($org: String!, $first: Int = 100, $after: String) { organization(login: $org) { samlIdentityProvider { externalIdentities(first: $first, after: $after) { edges { node { guid, samlIdentity { nameId } user { login } } } pageInfo { hasNextPage endCursor } } } } } ```
