title: How to add b2c-extensions-app in Azure AD B2C
body: <p>I have created a few B2C directories using the classic Azure portal.  Sometimes it adds the b2c-extensions-app but other times it does not.  When I delete a directory, Azure seems to have a long memory which prevents me from trying to recreate it (with the same name).</p>
  
  <p>Is there a way to manually add the b2c-extensions-app such that it shows up under "Applications my Company Owns" listing?</p>
