Where's "Welcome to F5 Networks" on Webtops

I spent a bit of time on this, so hope this helps someone else:

Access > Policies/Profiles > Customization > General. Click the "Text" tab in the left pane. Open Webtops folder, select your webtop > Full webtop settings.

In the BIG-IP management GUI, under Access Policy - Customization (Advanced), click on the Localization tab. Drill down to Customization Settings - Webtops - [your webtop] - Full Webtop Settings - Header Message.

It looks like I have to change the webtop_header_message based on the below. But I can't find this variable...

  
                 
    %[disconnect_text]
  
  
     
     ">
  


It’s coming from this page: 

/webtop.eui?webtop=/Common/apm_webtop_&webtop_type=webtop_full

Thank you for researching this and providing this valuble "how to" guide.  Very useful.
