how does replacing the original values that were sanitized from PII plugin work?From what I know, presidio only replaces original value back if we tell it what all places it needs to do the replacement. do you have a wrapper to get response from LLM and put the original values back, by keeping a map of values that were sanitized. Also, the custom pattern match has fields: Name, Regex, Score but does not have context field.. without context, the score is irrelevant as regex matches are binary. and for the check box fields of Built-in categories do we have a score defined as some default values ? do these filters have some threshold score..?
