How to get an OCR confidence score?

I am looking at the early OCR results I did not find a confidence score. Is there

Our RPA OCR software does not return a confidence score yet. This is a very tricky issue and many (all?) “big name” competitors like Abby or Microsoft Azure OCR do not have such a feature either (yet). We are working on it!

Of course, what you can do already is to use engine1 and engine2 for OCR and compare the results. Text and/or numbers detected by both engines have a high confidence level of being correct.
