Possible approaches

• use puppeteer - this would probably implemented as an optional feature (as forcing user to install puppeteer with this package is a no-go), user need to install puppeteer for this and turn it on.
• use html2canvas. However this requires user to manually run it and save the image as part of the repositories. We probably need to render a dev only panel that allows us to run this in dev server. This may be a good approach, combining with File System Access API.
