Is it possible to apply a CSS fix as an SPFX extension to remove the library picker dropdown in SharePoint? We have over 400 document libraries with confidential client files, and we're trying to restrict access to only authorized users. Despite assigning permissions to individual libraries, users can see all the libraries in the site, even those they have no permission to access, using the library picker dropdown. We found a suggestion in the Microsoft Community to use a CSS fix as an SPFX extension, but we're not developers. Has anyone applied this fix before? Could you provide the source code? I apologize if this issue has been addressed before, I couldn't find it. Thanks in advance!
