Confused about what column_conditional_tooltips -> if -> filter is expecting

I am trying to figure out what the dash data table->column_conditional_tooltips->if->filter is expecting. I get that it is a string but I can’t find any example inputs. My goal is to show a tooltip based off of the value in a cell. My thoughts would be ‘filter’:‘value == bob’ . The tooltip text might then be “pencils and erasers”. If the value is ‘joe’ then the tool tip text would be “pens and paper”. That way the filter shows the tooltip based on the value that is in the cell. All I could find in the docs is " The if nested property filter refers to the query that must evaluate to True. " but I’m not really sure what data gets passed in or how to structure the query.
