How to extract a specific segment (e.g., 037832) from a bank statement line using Parse Rule set

Summary:

I have a bank statement line like this:

TRF/PAY/TOP-UP ECHANNEL|037832||1946812360024809|S1BPTBA088

From this line, I want to extract the value 037832 as the Reconciliation reference using a parse rule. I would like to know how to properly configure the rule so that the system picks up 037832 and sets it as the reference field.
