To only hide it for regular users, you can make a slight adjustment to the above CSS:
body:not(.staff) {
[data-section-name="community"] {
.sidebar-section-header-button {
display: none;
}
}
}
so now it will only apply to users that are not staff
We have a tutorial about how to make these kind of CSS changes here: Make CSS changes on Your Site
are people expecting it to add a sidebar item rather than create a new topic? or something else?
