Thanks Baertram, your snippet works well. I looked at your WishList AddOn and my code looks like this.
Is there something here that also needs to be addressed or is the code okay?

function ESOFarmBuddy.LinkContextMenu(link, button, _, _, linkType, ...)
    if button == MOUSE_BUTTON_INDEX_RIGHT and linkType == ITEM_LINK_TYPE then
        zo_callLater(
            function()
                AddCustomMenuItem(GetString(ESOFB_MENU_TRACK), function() ESOFarmBuddy.TrackItemFromLink(link) end, MENU_ADD_OPTION_LABEL)
                ShowMenu()
            end
        , 4)
    end
end
 
LINK_HANDLER:RegisterCallback(LINK_HANDLER.LINK_MOUSE_UP_EVENT, ESOFarmBuddy.LinkContextMenu)

Another question: Is there any way to add a context menu entry to auction house result items?
