Nurelic Extn Printing PII data

[khirod-dev]

HI , We are using "apollo-newrelic-extension": "^0.1.1" package with our GraphQL implementation at server side to see the Query details . We see that in Nurelic, Variables values are populated (Which is fine). But, it is a security concern. As some time when request contains PII data it is getting logged in Nurelic as Plain Text filed. I believe Following code is printing the variable values

newrelic.addCustomAttribute('gqlVars', JSON.stringify(variables))

Is there any way we can interject that before printing to remove PII data or obfuscate the PII data by a custom function ?
