Change log pipeline

I want to write a pipeline which can tell what field is modified in a table.who modified it and when . Below is table structure I am using.

Table name,field name,modified by,modified date,action done(replace,add,delete).

I am using quickbase action but it can't tell which field is modified . All other videos and link requires that modified field name should be known beforehand if using pipeline. I also don't see any option in pipeline where we can get field name . Can anyone please help.
