f5 AI Gateway pii-redactor not working

I am testing Ai Gateway by looking at NGINX Modern Apps Docs. I have verified that OWASP LLM 01, 07 are working, but 02 Sensitive Information Configuration does not seem to be working. The demo video also contains Sensitive Information related content.

how config Sensitive Information masking for ai gateway?
