That is a API breaking change. Should have added more initially, was a quick hack to get it out....
Maybe use the trp2.convert_queries_to_list_trp2 (https://github.com/aws-samples/amazon-textract-textractor/blob/d324b360dec724fc40bf46fe9f2441e8e403903f/prettyprinter/textractprettyprinter/t_pretty_print.py#L147)

Or we can add another method. Often customers want bounding box information as well, makes sense to output in different formats maybe.

oh didn't see that, we can maybe add a option with default to no in that function similar what was done in that function.

but yes also another object would work well.
@noxqs what's your take on it?

I think that could work also..
I depend on this feature as confidence levels are important.
Its one of the two methods I have to offer feedback to my client re failing OCR.
For now I monkey patch (sorry) get_query_answers in my projects, I understand this request is API breaking but to me the OCR result is only as good as the confidence level.

@schadem are you fine with the suggested solution if so I will update the PR.

It should be a new method as it is an API breaking change and impact customers already using the existing method. @tb102122
