If she doesn't have DRM enabled, you can use any of the popular video downloader extensions, or install an 'Allow Right Click' extension. If DRM is enabled, that's a trickier process, but there are guides on this site that explain how to do it.

Maybe this will work?
Not sure if it works but try right clicking -> inpect (F12) -> Network tab -> refresh page with network tab open and search through to find the content and right click to open in new tab. Sometimes you can save directly from there but if not copy the link and bring it to a online downloader ex (https://
