The submenu is only shown when there are actual actions to perform, and that depends on permissions/configurations.
To send email, you must configure an email address for that extension using fop2admin fop2 buttons
To add/remove/pause from queue, a queue button must be shown on screen, and you need all,queuemanager or queueagent permissions
To chat, you must have a license that includes the chat feature
If no conditions are met, the menu is actually empty. That is what's happening in your case.
