Hi Arjun,
You may find it easier to install the VS Code extension. It will allow you to make a lot of these changes through the VS Code user interface.
Please find the extension here: SailPoint IdentityNow VS Code Extension Now Available
You can then add a filter to it like the below, to indicate which accounts to NOT read in:
"filterString": "(Load__c==\"on_hold\")",
Thanks,
Margo
