Scim connector custom headers

Hello,
Im trying to set a custom header for SAP Datasphere “x-sap-sac-custom-auth” as mentionned in their doc. It works perfectly on postam and I manage to list users, On sailpoint I did a scim connector and tried to add the header in connectoAttributeslike this “oauth_headers”: {
** “x-sap-sac-custom-auth”: “true”**
** },**
When I aggregate it returns success but 0 account. Anyone has seen this before ?

We also have a similar requirement for a SCIM application. Were you able to figure out the issue in here?
