Hey there! Thanks for your contribution :)

Seems like this change is a little too drastic though. It disables the toolbar for any docs page. I believe the issue you're referring to mentions to disable the toolbar only in "unattached" docs, which is when there are no actual stories. Still, community addons do all sorts of things, so I'd assume users might want to be able to toggle the toolbar.

Thoughts @MichaelArestad @cdedreuille ?

Ah I see, sorry I think I got confused about that, I will update the PR @yannbf

Thanks for the PR @jatinparmar96. As @yannbf suggest, we don't want to always hide toolbar. Something like this comment suggests would be more valuable. #22081 (comment)
