Acrobat: Image enhancement from camera

Good afternoon,
In Acrobat, the interface of the Scan and OCR tools changed a few months ago.
In particular, the function Improve image from camera.
A blue message appears in the bottom right-hand corner, but then, after setting the borders, I cannot find any button to activate the image enhancement.
I attach a screenshot.
Thank you for your help.
