I cant open google classroom documents with libre office. Any suggestions please

What do I need to do to access google classroom documents. They won’t open with libre office. Any Suggestions please?

Please explain “google classroom documents”.

Google Classroom stores documents in Google Docs format. You can download them converted to other formats. This video https://www.youtube.com/watch?v=OXc7-GAyYOw shows how to do it. You will notice that .odt open document document format is one of the options. You can also edit Google Docs if you use the Chrome browser with the extension Google Docs Offline. Normally if you are using Google Classroom you edit documents online in Google Classroom.
