Hide the Nintex Workflow Context Menu

Hi,  

I wish to hide the the Nintex Workflow contextual menu (when you click your name in the top right corner in SharePoint). In order for me to do it through a feature, I'd need the folowing information:

<HideCustomAction Location="Microsoft.SharePoint.StandardMenu" GroupId="PersonalActions" Id="????" HideActionId="????" />

Thanks
