Automate PII detection across a large schema

Claro has grown rapidly and now has over 200 tables across its production schema - containing user profiles, credit scores, repayment records, financial events, and regional data. The compliance team needs to identify which columns contain personally identifiable information (PII), but manually inspecting every table is not feasible. They want to use a Snowflake-native feature to automate the identification process.
