Google changed how Gemini annoyingly bursts onto the scene every time I create a new Google Sheet.¹

I’ve updated the script in the original post so that you can still make that annoying sidebar go away.

1. I suggest typing sheets.new straight into the address bar.
   
   You can also use docs.new for slides.new for, yes, Google Docs and Google Slides respectively–but why would do that when there’s Canva? ↩︎
