OCR Extension will not operate as described

I have the LibreOCR 0.1 extension installed and a was expecting to see a new icon to download images to be read. The icon is not appearing on the toolbar nor is there any finds within the Tools-Customize search for OCR. The correct Adobe is installed. (using LibreOffice version and Windows 10) What am I missing?

This is a site for questions and answers about LibreOffice. Reporting problems of any kind is out of its scope. You should better contact the respective developer(s). It is notable that the extension has a version that implies a very early stage of development, thus, problems are almost inevitable.

It looks like the extension is for version 5.1.

Additionally: The extensions uploads your images to some OCR service in the internet. So be careful regarding privacy.
