Understanding Line Break in Watson Conversation

I would like Watson Conversation to display a response message from Watson with a new line.
Even if you try the following methods, they will not break the line.

　Oh, my God. 　Kakikakeko

Enter the following in Dialog's "Then response with:"

US>Aye\nKakikakeko
US>Aye\r\nKakikakeko

If you check Try it out...

US>Aye\nKakikakeko
US>Aye\r\nKakikakeko

appears as it is.

I tried the following method in Json Editor, and the result was the same.

US>Aye\\nKakikakeko
US>Aye\\r\\nKakikakeko

How do I get Conversation to write a new line?
