Prompt user to scan physical document

What’s the best way to implement in RPA a step in the process requiring the user to scan in a physical document?

Often the user will have to specify scan settings, select crop area, readjust the document on the scanner etc. and the workflow will have to detect whether the user is done with the scanning.

You have to go for attended bot, where bot will wait for user’s go ahead to start the scanning… ie
prompt a message “Please adjust the scanner…once ready click on OK”…something like this…

For the first step: I think @skini76 approach should work fine.

For the second step: Try to monitor the folder and see if there was a new document sent by the scanner. Check the timestamp of a sorted folder and see if it is below 1 min for example.
