SCIM isn't an option in Directory Integration

I'm trying to enable Automatic Provisioning via Azure AD, but the option for "SCIM" mentioned in the documentation isn't available in the Directory Integration section. It will update existing users, but whenever a new user is supposed to be created I get the following error:

Error code
