Thank you Paul, I’m not sure how I missed update user, that one is working as you mentioned.
Regarding the group values, I might not be using the correct terms, the desire is to have attributes set at a group level rather than a user level.
In the Okta UI I am able to define what appears to be “group level” custom attributes for each app assignment, I am able to fetch these with this Okta API:
https://developer.okta.com/docs/api/resources/apps#get-assigned-group-for-application
Unclear on how I can set these values via the API
