Does Flexera One App Broker deployment still use the SCCM query to get user/computer/relationship data with sync query like on premise or is Flexera One always integrated with SCCM?

If so can that be seen somewhere or just the FNMS inventory view with assigned/calculated user?

Please elaborate on any SCCM query being done, customer is wanting to know load on SCCM of any queries and other functions requiring what started out with request to SCCM team to set service account with Operation Administrator  role .
