6. (Optional) If you are using a custom dialog:
   1. In "conditions": "#greetings", replace #greetings with the intent name that triggers the greeting dialog.
   2. In "previous_sibling": "node_1_1507185247030", replace node_1_1507185247030 with the previous sibling node of your dialog.

The user greeting is added in front of the welcome message according to the User Name Presentation configuration in the chatbot general settings UI.

If an end user's full name is Jonnie Boxter, the welcome message displays:

• Hi Jonnie Boxter, if you have configured to display the full name 
  
  
• Hi Jonnie, if you have configured to display only the first name
    
• No user name is displayed in the greeting if you have selected None
  
  

If the getWelcomeMessage action returns an error, the user is greeted in the Hi <Full Name> format, in the welcome message.
