 +|createPromptControllerFactory|Create prompt controller factory.| 
 +|getUiContainer|Get UI container.|

 +  <behavior type='ECBehaviorPlayerLookAtInteractPrompt'>
 +    <!-- optional: use BaseGameApp command manager. game can add more supported values.
 +                   default is 'default' -->
 +    <string name='commandManager'>default</string>
 +    
 +    <!-- optional: use BaseGameApp binding manager. game can add more supported values.
 +                   default is 'default' -->
 +    <string name='bindingManager'>default</string>
 +    
 +    <!-- set element properties. omit property prefix if used inside behavior tag -->
 +    <integer name='.bindingIconHeight'>32</integer>
 +  </behavior>
 +</elementClass>
