I have 100 documents (with 4 different styles) stored in the folder, How do I extract those document, I tried to use for each loop activities preminarly, to make sure the robot will processes every file in the folder, unfortunately digitize document activities in document understanding failed to process the file onne by one in the document path. It just pointing one document and one process.
