// Based on https://help.zoho.com/portal/en/community/topic/how-can-i-clear-out-a-value-in-a-field-or-set-it-to-null-using-zoho-flow
// But this one allows blanking out multiple comma-separated fields at once
// Example module = "Leads" (without quotes in Zoho Flow)
// Example fieldNames = "Street,City,State,Zip_Code" (without quotes in Zoho Flow)
