Option to hide "One or more master keys need a password" warning

I have few not books which I don’t want to readable in all the Joplin installation.
I have created a new local notebook with new encryption key. But I see constant “One or more master keys need a password” top bar in all other installation location and it bit annoying.

Is there an option to hide this warning message?

The simplest way to hide on Desktop would probably be through CSS. Here is a post explaining how to find the class you need to hide: Custom Css for note editor (markdown).

Then you’d add that class to userhrome.css with display:none. Since I don’t see that banner I am not sure what the class is.
