Hide Staff Notices from non-Staff

We used Staff notes for tagging a topic with a link to a ticket in our ticketing system, which we don’t want visible to non-staff.

It appears that something like the following will work for us (thank you @Lilly):

.post-notice.custom {
    display: none;
}

.staff .post-notice.custom {
    display: initial;
}

Agree that this isn’t particularly safe, just need to do something stopgap until we transition away from this usage.
