.SKP File Viewer

I am new to SketchUp for Schools. I teach at a Microsoft school, so my students save their files to OneDrive. In the StudentVue Synergy LMS, students submit their assignments to the Drop Box from their OneDrive. The problem I’ve encountered is viewing the submissions in order to grade them. I am working remotely from a school laptop, I am not authorized to download an .skp file viewer and the tech specialist cannot download remotely. Is there a web based SketchUp viewer? I just need to be able to view the 3-D files, not edit or save them. Thanks
