As noted in another thread (https://support.okta.com/help/s/question/0D50Z00008G7Vbd/populating-manager-attribute-for-slack?language=en_US), Slack expects the Slack user id to passed.
We don't currently have AD so the resolution doesn't seem relevant. Is there a method to use the ExternalID of the manager from Okta slack appuser profile to be used for the "ManagerID" attribute?

Can you not go to the editor and change whats flowed from manager to externalid?
