PDF OCR Lesson

I'm working on the PDF Automation - Part 1 lesson. At 8:51 we need to click on the "Screen Scraping" button on the ribbon, however the current version of UiPath doesn't look like it has this, so I searched for OCR and used the "Get OCR Text" activity.

I updated the OCR engine to Tesseract instead of the default UiPath engine (since it generated an error) but I still get the following error message. Any ideas on how to resolve this?

TIA!

Source: Find OCR Text Position 'client'
