What will be the response for the update request of a non existed user in OKTA SCIM API?

What will happen if we call update for a non-existing resource in OKTA SCIM API using PUT operation (https://developer.okta.com/docs/reference/scim/scim-20/#update-a-specific-user-put) ?

Does it return 404 or it will create a new user?

@LBJP This can be verified in your SCIM server. Do you have a SCIM server? If yes, you may call this endpoint and get a response from there.
If you think the response is not correct or unexpected. You can open a support ticket through an email to support@okta.com with this issue.
