AddCommandMenuItem and Instructor Figure Notifications / Supports

[Kydoimos 916]

Hi all - totally confused with this - hence the rather garbled title for this thread. I like the supports that appear in the new campaign and I would like to try and do something similar. Essentially, what I want to do, is to add a support item. You know how the little exclamation mark or other similar icon pops up? I'd like to achieve that and then when I select the support from the menu, I'd like it to fire a script and make the icon disappear again. I have found this:

class CfgCommunicationMenu
{
   class myArtillery
   {
       text = "Artillery Strike"; [color=#0000FF][i]// Text displayed in the menu and in a notification[/i][/color]
       submenu = ""; [color=#0000FF][i]// Submenu opened upon activation (expression is ignored when submenu is not empty.)[/i][/color]
       expression = "player setVariable ['BIS_SUPP_request', ['Artillery', _pos]];"; [color=#0000FF][i]// Code executed upon activation[/i][/color]
       icon = "\a3\Ui_f\data\GUI\Cfg\CommunicationMenu\artillery_ca.paa"; [color=#0000FF][i]// Icon displayed permanently next to the command menu[/i][/color]
       cursor = "\a3\Ui_f\data\IGUI\Cfg\Cursors\iconCursorSupport_ca.paa"; [color=#0000FF][i]// Custom cursor displayed when the item is selected[/i][/color]
       enable = "1"; [color=#0000FF][i]// Simple expression condition for enabling the item[/i][/color]
       removeAfterExpressionCall = 1; [color=#0000FF][i]// 1 to remove the item after calling[/i][/color]
   };
};

So, I can add it to the description.ext ok. But I'm a bit muddled on how I call it or how I use it to call a script from the command menu. Sorry - I just need this explained to me in simple terms. I'm no pro with scripting and I'm still struggling to find my feet! Thanks for any help!

Thanks IndeedPete - you covered it here already! However, I'd be interested to know how the InstructorFigure function works..?
