Documentation of SCIM (System for Cross-domain Identity Management)?

Hi! Didn’t even know Directus supports SCIM until I saw it mentioned in the recent thread asking for feedback on Directus license revision. We are self-hosting and trying to map out the support for auth and provisioning (and what logic to add ourselves). Even the equivalent of the auth env var configuration would be helpful (https://directus.io/docs/configuration/auth-sso) to try to understand this. Thanks!
