Hide a "link" in dashboard

Hi there.
In my navigation bar I have tabs and links.
I use the ui_control node to hide/show tabs or groups, but I dont know how to hide the "link" ones.

I've tried:

msg.payload = {
    "tabs": {
        "hide": "my_tab_1"
    },
    "links": {
        "hide": "my_link_1"
    }
}

but no sucess.

Any tips?
