Accessing Netsuite Connection Details

I have a custom flow to create Purchase Orders in Netsuite.

I can retrieve the Purchase Order Id (eg:938073) in the Response data, but is there a way for me to identify in realtime the Netsuite System ID or otherwise create a URL that will link directly to the created Purchase Order to make the flow portable between sandbox and production:

Example URL:

https://12345678-sb1.app.netsuite.com/app/accounting/transactions/purchord.nl?id=938073
