How to use Microsoft Cloud OCR with Computer vision API correctly

Hi I was trying to use Microsoft Cloud OCR and ran into an issue.
I got the 7 day free trail of Microsoft computer vision API and got two keys Key 1 and Key 2

I copied them and tried using them inside UiPath Microsoft Cloud OCR but it is not working it gives error.

Have anyone tried it, do we need to authenticate those key somewhere?


The only error I receive is within the output window stating it cannot access the file because it is being used by another process??
