Is it possible to modify the ribbon toolbar in document library viewer?

Hello, I was checking the video here https://www.catapultsystems.com/blogs/customize-sharepoint-document-library-form-using-power-apps/ and was wondering if it would be possible to add buttons with additional options to the toolbar menu of the default document viewer https://www.dropbox.com/s/muyc4aqkdhs1by2/Sharepoint%20Lectura%20documento.png?dl=0

Some of the options I would like to add is a "reading confirmation checkbox" and a "score rating menu"
