Works with WordPress 5.1.1

I tested in in WordPress 5.1.1 and it is working perfect. I logged in as myself (admin) and saw my userID in the dashboard metabox: Who’s logged in. In another browser, I logged in as another user (editor) she does not see this metabox in her dashboard; but I saw her name below mine. She logged out, and her userID disappeared from my dashboard.
That’s all I need. Thanks
