Need Tutorials and Guides regarding IntelligentOCR

Hi there. I want to learn Document Understanding but other than a 17 minutes video in
UiPath RPA Platform 19.4 Updates tutorial in Academy and the docs which of course is a reference, I couldn’t find more. Maybe I’m bad at search but would you please give me links to some resources regarding IntelligentOCR (as I guess it’s what referred to as Document Understanding among UiPath). So many thanks.
