Draftback and Google LTI 1.3

[sself]

We are utilizing the draft back extension to help combat AI generated writing. When my teachers utilize the Google LTI 1.3 and open the doc for grading, the draftback extension is not there. If they access the papers through the Google drive folder structure, the draftback option is available, but of course this is quite a bit more tedious. Any ideas why the extension wouldn't be available through Canvas and the LTI grading screen?

Could you share a screenshot of what you can see as far as the Google Docs menu? Do you have the Extensions menu available?
