Which part? Which one?

https://docs.sentry.io/organization/authentication/sso/azure-sso/#scim-integration

Description

The SCIM integration will create users in Sentry, but it is not documented how the users attributes are supposed to look like in Sentry.

Suggested Solution

Document which Azure/SSO attributes are translated to the user settings in Sentry: Name, username and email address.
